justified. If the device is not bottom justified, AutoSite will not be able

to read or program the device.

3. Lock the device into place by pressing the socket lever down.

Note: Insert DIP devices into AutoSite AFTER you have installed the DIP Base

in AutoSite.

Inserting PLCC

Devices and Using

MatchBooks

Read this section if you will be using the Stand Alone Kit (a PLCC Base

and a set of MatchBooks) to program PLCC devices.

Data I/O has developed a new method to accommodate the special

nature of PLCC packages. The method uses the MatchBook, which holds

the PLCC device in place on the PLCC Base. When the device is locked

into place, the conductive pad on the bottom of the PLCC Base forms a

conductive path between the pin drivers in the pin driver head and the

device in the MatchBook.

MatchBooks do away with clumsy and expensive sockets and adapters,

and make inserting and removing surface mount devices much easier

and faster. MatchBooks eliminate the guesswork involved when you

insert a PLCC device into a socket. All you have to do is align pin 1 and

set the device in the MatchBook.

Inserting a Device Into a

MatchBook

The instructions below explain how to use a MatchBook and how to

insert and remove a device from a MatchBook.

1. Insert the PLCC Base into AutoSite. Lock the Base into place. See the

section titled “Inserting the DIP or PLCC Base” for information on

inserting the PLCC Base.

2. Select the MatchBook for the device you are going to use.

3. Insert the MatchBook into the PLCC Base as shown in Figure 3-12.

First, set the front edge of the MatchBook onto the PLCC Base. Then

lower the back edge of the MatchBook into place on the Base.

4. Insert the device into the MatchBook, as shown in Figure 3-13. Make

sure you insert the device according to the alignment diagram on the

MatchBook. Close the MatchBook.

Note: Position the device so pin 1 is near to the retaining clip. There is a small

dot molded into each MatchBook to help you align your device. Each

MatchBook also has a beveled corner to help you align devices with a

chamfered corner to indicate pin 1.

5. Finally, close the MatchBook and press the retaining latch forward

with your thumb until the latch snaps into place, as shown in

Figure 3-14.

Removing a Device

From a MatchBook

To remove a device from the MatchBook, unsnap the retaining latch,

open the MatchBook, and lift out the device.
