We have heard a lot whether the PCB printer machine and FPC printer machine, circuit board machine, especially manufacturers in the circuit board industry, many have begun to apply ink coding or laser marking to replace labor, save labor costs and improve efficiency. Today, we will share with us the detailed application status of PCB printer in the circuit board industry.
There are many processing process of circuit boards, including cut sheet → inner film → inner etching → inner test → Browning → layout → pressing → drilling → PTH → Outer film → plating → Outer test → Legend → Gold finger → surface treatment →Routing → Electrical test → final inspection → Packaging → shipping so on.
In the PCB factory these links also have a lot of central is able to use the printer identification equipment, after the printer identification equipment assigned code, can be generated for each circuit board serialized identification, in the later consumer processing process can be based on evidence, sources can be checked, obligations can be investigated, to complete the quality assurance of consumer quality.
Whether it is a circuit board printer, or a circuit board laser marking machine, it is a more vague concept than according to the detailed point of view, mainly small character printer in the PCB circuit board industry scene application, after the detailed inkjet application show, so that everyone can open up thoughts, in the selection of PCB printer more relaxed, accurate, improve efficiency. Alternative to manual stop circuit board identification: one board one code.
First of all, we see the electrical testing workshop. In the electrical testing workshop, every circuit board needs to be stopped by the equipment to test the on-off status of the circuit. After the testing, the equipment will issue a PASS or FAIL instruction, and the profitable inkjet machine can accept these instructions and complete the serialized printer work. Print a serial number for each PASS circuit board.
The content of this serial number can be a string of English plus numbers, representing the status of each workshop, shift, and team, which can be traced back in time when the problem is presented, find the problem batch, and complete the improvement and recall work quickly and efficiently.
