Most of the PTH components are manually inserted. Some are auto-placed by our UIC machine. The parts are preped before install, so there is no need to trim the leads afterwards. The boards go through wave solder. The UIC machine has a clincher on

Hi, If your PCB is large, you waste a time. Any picture, you takes, will be with corner distortion. I suggest you to: 1. use AOI (manually or automatically) 2. try simulation of your PCB production before real SMT production process 3. use human FAI

I have rarely seen a bad SRX controller card but it sounds like you may have a faulty card. Since i know you have 2 machines...i would swap them....make sure you take a picture of it or write down where all the cables plug in. The SRX board is locate

As with most questions the answer is; it depends. Provided not too many boards are set onto a panel we use a .10" router gap around the PCB and .10" wide perforated tabs. We do request customers specify where they do not want tabs to ensure no breako

Dave is right, though apparently a bit grumpy today. What he's saying is that the ring de-wetting is a bad thing, and should have been called out by your lab. You might consider a lab change in the future. Some information about your processes, an

Are you using lead or lead-free solder? 260C would be good for lead solder but may be a bit low for lead-free. We run our lead-free selective solder pot at 300C although we do not have any pre-heat or top heat, just hot nitrogen blowing around the

I'm not completely sure what you're asking, but, I can say that I've placed these parts with MyData's and Philips machines. Pick in the center of the part, and place in the center of the outline, and the terminals should line up with the pads on the

Hi, I would check the thing in the following order. 1. Check paste - SPI is the best way. If you don't get the right deposit there is no wonder you have issues. 2. Check reflow profile - tweak it to the point of perfection for the board you have. 3

Jimmy: Make sure to look in and around the board to make sure you have captured all locations of solder balls/fines as they are commonly caused by the profile or print issues. If they are non-embedded and are a 610 defect based on the class of your
