1. MAKE SURE THAT THE ENCLOSED ADAPTERS ARE THE APPROPRIATE SOCKET TYPE FOR YOUR APPLICATION - on initial orders, an LCC socket adapter is sometimes ordered when a PLCC/PCC is what is needed.
2. MAKE SURE THAT THE SILK SCREEN NUMBERING MATCHES YOUR PART - Some devices are numbered starting with pin 1 in the upper left-hand and some starting with pin 1 to the upper center of the package.   Some chip manufactures offer devices using both numbering schemes.   This may be a problem with the J-leaded (PLCC/PCC) type packages.   Electronically there is no problem, the silk screen on the adapter circuit board just will not match the real component pin numbering.   The enclosed adhesive backed numbering sheet could be used to re-label the component side silk screen on the adapter if necessary.

Overview

  These wire wrap prototyping adapters give the designer a choice of either a production or test socket on a numbered circuit board with test points on the component side and a choice of either wire wrap pins or gold plated machine pins for mounting.   For most prototyping, where the SMD component is just a non-programmed controller or peripheral chip, the lower cost production socket provided on the ANC-9000 series is used.   In applications where the SMD chip will be repeatedly inserted and removed, for testing or programming, the zero insertion force test socket of the ANC-8000 series series is recommended.

Introduction

  Thank you for ordering our adapter products. Antona Corporation has been producing process and monitoring control cards and systems since 1979.   Our engineers were eager to develop new card products for the industrial control market using the new leadless chip packages, only to find that there were few products available to interface the multi-pin leadless, plastic and pin-grid chips to wire-wrap posts in order to prototype the   initial design.   During the design debug stage, the difficulty in getting an oscilloscope probe onto the chip produced a secondary problem.   Locating a particular pin number on a package with so many leads, and then holding the scope probe in place on the edge of a lead with center-to-center spacing of 0.050" or less proved to be a frustrating and possibly disastrous operation.   Hand fabricating an adapter, depending on the number of pins, requires 2-6 hours (and then may not work properly).

  After developing an adapter series for in-house use which solved all these problems, and at the encouragement of fellow engineers who had faced the same problems, we introduced, in 1985, a line of adapters to accommodate a wide variety of package types.   In 1991, LEDs were added to the adapters to provide a unique feature to aid in design test and debug.

  The ANC-9000/8000 series provides a quick and efficient means for the circuit designer to wire wrap prototypes of equipment using VLSI leadless and leaded type packages.   The adapter series was designed to bridge the application gap between these types of components and the prototype stage of system development.   Occupying a minimum amount of card real estate, the adapters provide labeled test points for each of the pins for the designer to attach oscilloscope or logic analyzer probes. The wire wrap pins are on 0.3" centered rows to allow the adapters to be used on a wide variety of prototype boards.   The tin plated pins extend .6 inch beyond the users prototype card when .062 inch card is used.   This is sufficient for 3 standard wire wraps to fit on.   All Antona adapter products are 100% electrically tested for proper operation (pin-to-socket continuity and no short circuits).

  If the adapter you ordered and received is not suitable for your particular component just call and explain the problem - please include the component part # and manufacture of the chip you are using if possible so we can add it to our reference list.   We can ship for next day delivery if need be.

Adapter Part Numbers

  Our line of adapters has now grown to over 150 types including custom versions.   All of Antona's adapter products are designated: ANC-9PXXV (or ANC-8PXXV for Test Socket Versions).   Adapters are added to our product line much faster than reprints of this manual, so check the Antona price list or contact the factory if you are unable to locate the adapter version desired.

  'XX' is the number of pins on the adapter socket (for sockets over 100 pins, use the lower 2 digits to specify the number of pins) and 'V' is the socket version type as described below:

A N C - 9 P X X V

Package/Pin type specification (P)
0 = PCC/PLCC/PGA/LCC with .025" squarewire-wrap
5 = as above with .018" gold machine pins
1 = SOIC with .025" square wire-wrap pins
6 = as above with .018" gold machine pins
2 = Plastic Quad Flat Pack - PQFP with wire-wrappins
7 = as above with .018" gold machine pins

Socket type specification (V)
L = Leadless Chip Carrier - LCC (JEDEC typeA,B,D), pin 1 in corner
T = LCC as above with pin 1 in center sideof chip
P = Pin-Grid-Array - PGA, pin 1 in corner of chip
U = PGA as above with pin 1 in center of chip
J = Plastic Chip Carrier - PLCC/PCC/J-Lead, pin 1 center side of chip
S = PCC as above with pin 1 in corner of chip

Hardware Considerations

  At Antona, the adapter cards are 100% inspected before, during and after assembly.   The yellow dot on the adapter socket signifies that it has passed a functional electronic test for open connections and shorts.   But even with all our testing and inspecting, the first time the product will actually be used in an electronic circuit application will be by you.   Please take a few minutes and inspect the adapter to your satisfaction. If an engineer or technician ran a simple continuity and short test on the 160-pin adapter, it would take about 20 minutes maximum.   Once all of the wire-wrapping has been completed, it will be nearly impossible to fix a broken socket lead or trace if it is located between the adapter card and the prototype card.   If you find something you are not happy about, call us.   Our policy is simple, if the adapter has been paid for, a replacement will be shipped that day.   If the item was shipped on open account, just return the adapter to us for a replacement.

  I know, as a working engineer since 1973, that about the last thing checked for on a design being debugged is a bad socket.   The first thing suspected is the design (the design task the other engineer was responsible for), then the wire wrapping, then the software, and then the operation of the component.   Somewhere, way down the list of suspected problems, is the socket.   Take as much time and caution as the worse-case possibilities warrant.

Adapter Mounting

The adapters should easily fit on any prototype card which has been laid out to accept industry standard .3" spaced rows of .1" spaced pins (except the ANC-8260 adapter which uses .1" spaced rows).   Some of our customers just cut a hole out to match the adapter footprint.   Make sure that once the Antona adapter has been installed in the prototype card that there are no conductive paths (bypass capacitors, component pins, etc.) under the adapter's socket which might short to the adapter socket itself.   The black plastic carrier, on the bottom of the adapter socket, provides a .1" space between the users prototype card and the adapter, but the socket leads sometimes come very close to the prototype card depending on the manufacture of the socket. The designer should take a few extra precautions when using the new generation of chips.   Spending a little extra time up-front will save a lot of grief (and rework) if a problem is caught early enough.

Adapter Wire Wrapping

  Note first of all, that with so many pins, getting out-of-step by missing or jumping over 1 pin will require unwrapping many wire wraps, and that is if you only have 1 wrap per pin.   Use the enclosed adhesive backed pin numbering sheet to label the pins on the wire wrap side of the prototype card. The enclosed sheet is also handy for labeling pins on any other component or connector pins on the user prototype card.   Suggested application of the numbering sheet is attached to the adhesive sheet itself.   Once the pins on the adapter have been labeled on the wire wrap side of the card, locating the correct pin number to wire to will be a snap and the chance of mis-wrapping a connection will go way down.   Frequent checks of pin wiring by continuity testing is highly recommended.   Use the silk-screened pin numbers on the top side of the adapter for this process. Try to avoid wiring more than 2 wraps per post.   As the design debug process proceeds, you may need to add a 3rd wrap (along with adding IC's, assured if it's one of my designs).   If the lettered pins, which may be used to connect to the on-board LEDs and/or corners of the socket, on the adapter are not being used, bend them over to a 45 degree angle to help prevent getting out-of-phase.

Machine Pin Adapter

  The same basic problems can crop up with the machine pin as the wire wrap versions of the adapter.   Gently pry-up the adapter if it is necessary to unplug the adapter from the prototype board because the gold pins are only .018" diameter and are very fragile.   If you do break one of the pins, they can be individually replaced with the proper desoldering and replacement pins (call Antona for replacement gold pins, within reason, they will be shipped free).

Component Installation

  Do not install the target chip until all wire wrapping is done. It is probably a good idea to measure the power supplies going to the chip adapter with a voltmeter or scope before chip installation.   Take a second look at the chip once you have put it into the socket to insure correct pin 1 positioning.   With the leadless chips (LCC) it is almost impossible to not install it correctly because the metal cover will not close properly if installation is incorrect.   The plastic chips or J-bent leaded parts (PCC/PLCC), have a corner cut away which the designer should install matching the upper-left corner of the PLCC socket located in the same corner as the cut-away corner of the adapter circuit board itself.   The PLCC chips require a special tool to remove the chip once they are installed.   Antona offers a low cost PLCC removal tool (ANC-PLC) The pin-grid-array (PGA) chips look like disaster in the waiting as they may be plugged into the PGA adapter card versions in 4 different ways with equal ease.   Make sure that pin 1 is properly positioned before applying power to the system.   If the PGA chip is to be removed from the adapter socket, use extreme care when prying up the chip.   A special PGA removal tool is highly recommended.   Plastic Quad Flat Package (PQFP) parts have the potential to be misinstalled also.   Be sure to identify pin 1 on the chip, place the part into the cover piece and then carefully press the device and cover onto the adapter socket body.

Power and Ground Considerations

  The designer should place bypass capacitors (.1 ufd) and a filter capacitor (15 ufd ) as near as possible to the adapter package wired to the Vcc and GND of the chip.   Keep the power and ground wires to the adapter as short as possible.   Solder connections wherever possible to power the chip.   Many of the leadless chips have multiple Vcc and GND connections, be sure to use all of them. Most of the ANTONA adapters have .015" traces of 1 ounce copper, which means each trace is rated at 1 Amp of current with a 20 degree C temperature rise above ambient.   All versions have .030" traces on as many of the solder side pins as possible. It is noted that there seems to be no standard pins set aside for Vcc and GND connections from manufacturer to manufacturer.   Depending on the particular component that the designer is using, additional heat sinking may also be required for proper operation of the part.   With the 68-pin LCC adapter, special heat-sink covers are available from Antona.

Adapter Socket Components

  The most important socket attributes are availability and price.   After trying several different manufacturers' sockets, and listening to our customers preferences, we have settled on a mixture of sockets for use on the various versions of the adapter cards.   The widest range of PLCC type components seem to be best accommodated by Yamaichi sockets and customers seem to prefer the AMP sockets for LCC type devices.   The wire wrap pins on the ANC-90XX/80XX adapters are tin plated 0.025" square posts. The gold plated machine pins on the ANC-95XX/96XX versions are 0.018" diameter and 0.150" long.   If your particular application requires that a specific socket be used, gold plated wire wrap posts, or .020" machine pins, etc., you may inquire with Antona Corporation about a custom run of adapters built to your specifications with a 6 piece minimum order.

Light Emitting Diode (LED) Feature

  Beginning in 1991, we started adding LEDs to the adapters as new batches of cards were manufactured.   Access to the LEDs is very straight- forward.   There are separate wire wrap leads (in no way connected to the component socket) which the designer may use to monitor supply voltage to the adapter and/or any user selected signal that can sink the 6 to 8 mA of current necessary to light the LED.   This feature is unique to the Antona chip adapter and chip test product line.   The application sheet enclosed with your parcel details the LED pin connections for the adapter(s) you have ordered.

Adapter Pin Arrangement

  The following pages contain enlargements of the silk-screen used on the adapter circuit cards.   The designer may use these as a layout sheet and debug aid by annotating the pin functions of the particular chip being prototyped directly onto this sheet.   The pin numbering follows two possible schemes, pin 1 in the upper-left corner (usually for LCC/PGA) or pin 1 in the upper-center of the package (usually for PLCC-PCC).   At some point in time the pin numbering will be standardized using a single numbering scheme.

  There are 18 pages of layout sheets included with the printed manual that accompanies an adapter order.   These are graphic files which would cause an HTML document like this to load to your browser very slowly.   You can look at a sample layout below to get an idea of how the family of diagrams appear.

  For a full size sample layout of our ANC-9044 adapter (60K), click on this thumbnail graphic.   You can then output the graphic on your printer (set printer to "landscape" output for best results).   The layout sheets in the printed manual are much sharper than this sample graphic file.
