In my limited experience. A Domestic Dishwasher with no water recycling like which is offered on some of the newer high priced models works a treat. Clearly this is batch. Inline filtering of the water supply is a good ideal. There are several ways o

Our model of machine does not do "blob analysis" so I'm not sure what you mean by that. "Pattern matching" will only pass if I set the pass percentage down to about 45% and I don't feel comfortable with that. When using a solder inspection everything

Absence of solder is just black/super dark red which still falls under any percent I could put in there. So it passes. Maybe I'm a bit confused on how the machine checks solder in general anyway... 0%-60% is a pass by default. Thats anything dark - s

We are a very small EMS that has been sued by a large OEM customer. We built a board, it passed the customer supplied tester, but we had accidentally put a wrong part on it. This was discovered years after we had been placing this part. The cust

With the bottom followed by the top set up, how do you even come close to balancing that? For a lot of boards that I have seen you would need five or more top lines just to handle one bottom line. Or have the bottom line on a very low duty cycle. B

I agree with Evtimov that sticking with the J-Std-033 is preferable to creating your own procedure at a different temp, especially if you need to pass an audit since the auditors will compare your process to the J-Std. My understanding is that oxida

Hi Everyone, we have here in our EMS supplier some finish goods that pass all our functional test but fail our final burning test. The burning test is a 30 minutes test which simulate customer use cases, during this test the product is subject to tem

Well, the story is a little more complicated. The product is also an LED lamp made on an aluminum PCB with the LEDs on one side and the drivers on the other. The board itself is not big, about 90x90mm and most of the components are soldering well. Us
