When testing unsuccessfully, the chip to this number is needed to re-start IC write-in, laser marking, vision checking procedure, and the core that will be mended
Piece is reentered into station locating for the IC verification agency (E) and is verified, and verification is further continued for carrying out after passing through；Period compiles currently
All chips after number chip stop entering verification station locating for IC verification agency (E), just need using rotating disc at this time
(1) four cache slots (2) on；Specific step is as follows:
Step J is in the chip of station locating for the IC verification agency (E), by the IC verification agency (E) to chip interior number
According to being verified, the subsequent chip in the upper four chip storage grooves (4) of the rotating disc (1) successively waits discharging at this time；It is in
The chip of station locating for IC verification agency (E) verifies failure, which is set to bad chip；
Step K, rotating driver (3) driving rotating disc (1) rotate 45 degree, will be apart from entry/exit material station (A) delaying recently
It deposits slot (2) and goes to entry/exit material station (A), the chip to number in order that the IC written agency (D) completes write-in is passed through into machine
Tool hand is put into the cache slot (2) at entry/exit material station (A), while by the chip of verification failure from the IC verification agency (E)
Place's station is dished out, and the IC written agency (D) suspends the write-in to subsequent number chip, writes one and the bad chip sequence again
Number identical chip；
Step L, after the completion of the same serial number chip for re-starting IC write-in, the rotating disc (1) is rotated by 90 °, will be next slow
It deposits slot (2) and goes to entry/exit material station (A), the same serial number chip of completion will be re-write from IC written agency (D) by manipulator
Locate station to take out, put into the cache slot (2) at entry/exit material station (A)；
Step M, rotating driver (3) driving rotating disc (1) rotation will successively go to laser marking station with serial number chip
(B) station carries out laser marking, goes to station progress printout surface information checking at OCR vision verification station (C) at, finally again
Go to station at entrance/discharging station (A)；
Step N will be taken out from station at entry/exit material station (A) with serial number chip by manipulator, and be put into the IC verification agency
(E) station re-starts verification at, and after verification passes through, then return to normal production process again, and the chip on rotating disc (1) is successively
Laser marking and the verification of OCR vision are carried out, the IC written agency (D) starts that subsequent chip is written.
