Simulating with what? In developed countries manual labour is expensive but is also still the most common solution to fitting though hole parts, even if the board are then wave-soldered. Mixing SMT and THT on what sounds like a very simple product wi

I've never seen this before and I would be suspicious. Have you tried to dust it off with a brush or Q-tip, it might just be some sort of process contamination. Have you looked at the reel to see if the parts are coming in with these spots from the

Hello! Recently started buying PCBs with peelable mask to remove the need for Kapton tape. Had no issues with our first batch, but our supplier has over-cured the second batch - it comes off in tiny bits, and is stuck in the holes. After timing the

Wave soldering inspection templates enhance the visual inspection process by guiding the operator's eyes to a specific location on the board to check for the presence and correctness of components. I feel that PCB visual inspection template should be

Hello, We have recently bought ZipaTec select 250, we are having problems with offsets. Somehow the offset of fluxer, wave and preheat dont match one another or the program we create. The previous owners are of no help. The main question i have

| Micheal, | | What does your profile look like for the wave? What profile does your flux say you need? My guess is it is not your profile, our testing with solder balls found that the mask on the boards was the largest contributor to solder balls

Hi Earl , Have you already got ProFlow installed on your DEK Machines ? - if so I would be interested to hear any feedback on it. That goes for anyone else using the system - or in fact the MPM Rheopump. K

if do not have x-ray inspection machine, how to verify the 1st board out from the smt placer that the BGA is placed accurately onto the solder pads. the diameter of the solder ball is 1mm. could it self align during reflow?

what process is that? can kindly describe? is it that technology where bricks of solder are "ready made" deposit onto PCB pads thus eliminating the need to solder paste print/dispense by machine?
