Preventive Maintenance

Conductive Pad

The conductive pad, the material the MatchBook rests on, should be kept

free of dirt to keep yields high and prolong the life of the pad. We

recommend that you inspect and clean the pad at least every 1000 device

insertions or monthly, whichever comes first.

Note: After a number of insertions, you may notice an indentation in the middle

of the conductive pad. The indentation is normal and does not degrade the

contact resistance or the performance of the MatchBook. It is also normal

for the pad to show signs of discoloration as it is used.

The life of the pad is dependent on proper care as well as the pin count

and package type of the device being used. Not all devices have the same

tolerances, and use of each device type may result in different life cycles

for the pad. If you experience an increase in device insertion errors or

continuity errors, or if you experience a sudden drop in programming

yields, the pad may need to be replaced.

Cleaning

Blow air over the pad to clean it. If you use compressed air, direct the air

stream from the front or back of the Base.

Note: To avoid lifting the pad off the circuit board, do not blow air from the side

of the pad.

To further clean the pad, apply a small amount of isopropyl alcohol on a

cotton swab and gently wipe off the pad to dislodge dirt. Make sure the

pad is clear of any cotton filaments left over after cleaning.

CAUTION: Do not clean the pad with any petroleum- or freon-based

products. These substances will cause premature

deterioration of the pad material.

Replacement Pad Kits

The Base has been designed to allow you to replace the pads quickly and

easily and to minimize downtime. To order a replacement pad kit,

contact Data I/O Customer Support as listed in the Preface.

SPA Block and Base

For optimal performance, keep the SPA block (see Figure 3-6) and bases

clean. The following messages during device operations could result

from dirt in the SPA block or base adapter.

ID Error

Continuity Error

Base Adapter not Installed

Device Insertion Error

Overcurrent Error

Base/Adapter Relay Failure

SPA Block Cleaning

To avoid error conditions caused by dirty or worn SPA blocks, we

recommend that you perform the following preventive maintenance

procedures.

• Keep the SPA block covered with a base or programming module

when not in use. To prevent base adapters from contaminating the

SPA block, store them in an uncontaminated area.

Operation

3-20 AutoSite User Manual

• Each time you remove or replace a programming module, clean the

SPA block with a brush.

• Inspect the SPA block and base adapter for dirt weekly. Follow the

steps below to clean the SPA block.

1. Blow compressed air across the SPA block.

2. Mildly dampen a small section of a lint-free cloth with a DeOxit

pen (Data I/O P/N 570-5500-901) and gently rub the dampened

cloth across all the pins on the SPA block.

3. Using a clean section of the lint-free cloth, gently wipe the surface

again.

4. To ensure that all pins are properly positioned in their

receptacles, push a programming module down on the SPA pins

a few times and check that the pins spring up to their normal

upright position.

Base Cleaning

Weekly inspect the bases for dirt. Clean the surface, including the

underside, with filtered compressed air. Clean with a lint-free cloth

dampened with DeoxIT if needed.

Isolating Programming Problems

If you are experiencing less than optimal yields when programming a

DIP or PLCC device, we suggest that you remove the AutoSite pin driver

head from the handler and try programming the device in the DIP or

PLCC Base.

If the device programs successfully in the Base, there could a problem

with the handler or with the programming module supplied by the

handler manufacturer. Refer to your handler manual for cleaning,

maintenance, and testing information.

If you experience programming problems when programming the device

in the Base, try to isolate the nature of the problem. For example, does the

problem occur during programming or during post-programming

testing? If you are unable to correct the problem yourself, contact

Data I/O Customer Support as listed in the Preface of this manual.

Updating the MSM (Mass Storage Module)

The Mass Storage Module is an internal hard drive that can be installed in

AutoSite. The Mass Storage Module allows you to store system and

algorithm files in the programmer, which can speed up the start-up and

disk access routines.

Installation

The MSM comes installed in all new AutoSites. If your older AutoSite

does not have an MSM installed, you can purchase one for your AutoSite.

Installation instructions are shipped with the Mass Storage Module.

Operation

AutoSite User Manual 3-21

Updating Software

To update AutoSite system software and algorithm files on your MSM,

refer to the User Notes

accompanying the new software.

Booting from MSM

After installing the system software on the MSM, you can boot directly

from the MSM by doing the following:

1. Make sure that drive A is empty.

2. Reboot or powerup AutoSite.

When AutoSite boots up and does not find a disk in drive A, it boots

using the system software located on your MSM.

Storage Capacity

The MSM is partitioned into four logical drives, as follows:

Storage Suggestions

Drives C and D are reserved for user data; drives H and I are reserved for

system use. Although drives H and I can be written to and read from, we

STRONGLY suggest you use only C and D to store your data.

Limitations

Other than the file operations listed below, drives C and D on the MSM

can be used for all file operations that can be done with a floppy drive:

Backing up the MSM

We STRONGLY suggest that you periodically make backup copies of the

files on the C and D partitions of the MSM. If the MSM were to “crash,”

you could restore your data files to C and D from your backups, and you

could restore the system files from the AutoSite disks.

Adding a New Programming Module

To add device support to your AutoSite, simply plug in a new

programming module and you are ready to use the new device support.

To add additional programming capabilities to your AutoSite, simply

purchase a new programming module and insert it in AutoSite. The

“Options” section of Chapter 1 lists the available programming modules.

File Operation Comments

Format Disk

Format only C and D. Formatting H or I will

render your programmer inoperative until

you restore the system software from floppy.

Duplicate Disk

Drives C, D, H, and I cannot be duplicated

using the Duplicate Disk command.
