12 Introduction
can program thousands of high-density chips per day.
Furthermore, the DATAMAN-848 supports two
programming modes. In standard programming mode, the
DATAMAN-848 automatically programs all eight chips after
all eight pieces have been inserted into the sockets. In
semi-concurrent programming mode, a user can divide the
8 sockets into two groups (of 4 sockets each). By using the
technique of programming 4 chips while simultaneously
removing and inserting the other 4 chips, a customer can
increase throughput. This also allows interface with the fine
pitch pick and place handler for high-density fine pitch
chips.
Statistic Functions
The DATAMAN-848 automatically keeps a running total of
all production pieces attempted and all production pieces
failed. Users can input a target quantity of chips to be
programmed and an allowable number of failures. An
alarm function can be enabled to send a message to the
screen alerting the user to either the target quantity of
chips being reached, or the allowable number of failures
being reached.
Fully isolated ZIF sockets
The DATAMAN-848 has fully isolated (> 1 M ohms) circuits
for each socket's address/data bus/control lines. Each
socket has its own built-in Vcc and Vpp current-limiting
circuitry. A defective device in one socket will not affect the
devices in or programming integrity of the remaining
sockets.
Device-insertion and continuity checks - No mistakes!
The DATAMAN-848 performs device-insertion and
continuity checks before programming each device. It can
detect poor pin contact, upside-down device insertion,
incorrect position, and pin number mismatch. This function
