Hi Jorge, The success of such production purely depends on process control. One needs to first understand the board layout in detail, and evaluate any critical components for their temperature handling capabilities. Remember, you are dealing with com

I am trying to make a PCB populated with complex components such as LGA, WLBGA, LGFP, LFCSP, VFBGA, QFN, FBGA, PBGA so that we can test out some PnP machines. I have found parts on digikey for each of the packages we want to test but trying to make

It depends on the board complexity and the volume you needed. For standard PCB in prototype and small volume, suggest you http://www.pcbgogo.com/b. For complex board (e.g. HDI board), suggest you fastprint and Yuwei. All of them are in China. Hope i

Hi This is a good one. Let me take a stab at it. First remind me, why is this air coming in carrying a charge. I think I remember yet it is always fun. Also hopefully it isn't carrying any compressor oils. There are some companys that make other t

How can one go about defining the complexity of a PCB for characterizing reflow profiles A large balanced board may be easier to profile than smaller unbalanced board ? Any ideas how to define an index to calculate the complexity based on size,weig

Hi, Yes did use that. but how to claassify a board based on complexity still remains ? Davef made a begining will appreciate if we have more comments Thanks

Hello, I'm considering to buy my first wave solder machine. We have small production, so we need an small machine, like bechtop wave solder machines. I have read that small machines as Novastar 8S, 12S, has some problems with complex PCB boards. Our

Take a look at the product here: http://www.kicthermal.com/products/KIC-Auto-Focus.pdf KIC uses a previously profiled product library to calculate in spec reflow profiles for new products. Just enter you dimensions and if finds a solution for you.
