From my past experience, you can usually get away with OUT the chip wave if your SMD's are no smaller that 0805, and more importantly, there are no SOT23's. A nice, clean, inerted laminar wave (with a little smart or omega help) will solder your S

If is IP-1, is using SMD2 vision instead of SMD3 (CPIV-IP3, CP6,7, etc) if so, you must use Vision Number instead of Vision type... if you're using fuji flexa just press F1 on vision number and you will se most common vision numbers depending on shap

We've never heard of a situtation where oversized pads caused voiding. Your supplier is correct that the pads on the board should be the same size as the pads on the interposer, but this is to improve reliability issues. Search the fine SMTnet Archi

Hi, I want to make a small setup for manufacturing PCB's based on SMD's for (pototyping boards, etc). I don't know clearly what are the equipments required for this purpose. I have an idea that we have to use (Pick n place station, Screen printing

Hello. We encountered a SMD problem on PCB. It is that the lead of photocoupler is shifted after reflow and don't meet the minimum requirement of side joint length. I know this is a defect but what i want to hear the reason and the solution to prev

Yageo announced their decision to stop marking SMD resistors back in 2013, and since then we have started to see 0603's that aren't marked, but larger sizes - so far - are still showing a value. 0402's have never been marked, and I doubt they ever w

Hi, I have a SMD radio module that has castellated Pads along one edge of the module. The pick and place machine appears to place them very well but when the boards come out of the reflow oven then up to 20% of them have either rotated a few degrees

Hello, I have searched the forums for this specific topic, but can not find the clarification I would like. I am setting up a baking system to "reset" SMD components using a vacuum-bake oven. According to the JEDEC-STD-033 standard, depending on th
