for reject rate depends on various parameters, Part data parameters, (Body tolerance,Part pickup & transport speed etc. ) Also depend on vaccum level, ( During the PM we need to messure pickup nozzle vaccumlevel using manometer ) According to raw mat

we face the problem to last month dry solder issue.when we found PCB is dry. (PTH not fill not properly)then we change the parameter like flux Tank pressure increase 130 to 250. after these activity PCB is ok no dry solder found......but problem is o

Anyone familiar with the K&S 4524A Wire Bonder? I'm trying to troubleshoot an issue: It fails to save or load programs. The tool will startup with the default parameters in program 1. The parameters can be changed but attempting to save to another pr

3 different A12 tools and the same error could be a problem with the tool holder or a parameter. I suppose the locking tabs in the holder could be worn or bent and you could try removing one of the pins from the tool and setting it in a different loc

I think temperature is the most under appreciated parameter. I'm not saying that it is the most important parameter, Just that a lot people do not give it the consideration it needs. I don't think it mattered as much in the old days of saponifiers an

The most effective method is to monitor both printing results and parameters. Periodically (maybe once per month), run QCCalc or another program to measure the machine's capability to hold its set parameters. I also run control charts on the paste h

A process consists of much more than just thee machine. When developing a cause and effect diagram ffor the process, there are many parameters that fall outside the machine itself. There are Man, Machine, Methods, and Materials. Just monitoring th

I think your solder mask is a partial cause of your solder balling. Additionally, adjusting some machine set-up parameters may also help. 1 If we were talking about a single assembly problem, we�d be thinking about the laminate, but since you say t
