Does anyone know of a vendor who manufactures pallets for PCB's. I have a couple of boards where the parts are too close to the edge to allow them to be placed in my Pick & Place equipment (nozzle will hit conveyor rail). I know that pallets are made

Has anyone seen or put together a good collection of proper handling procedures for components and PCB's? I realize a lot of it is no-brainer stuff, but I need some depth for a training class we are putting together. This would include ESD, Moisture

Hi Kurt, I agree with Dave F. I had exact same problem with PBGA placement. We requested our PCB vendor to plug/tent via (button printing) after HASL with SR1000 which worked well in the long run. There are couple of failure modes associated wit

Hi Russ, I thought about it and what approach I would do. All that talk about causes and reasons doesn�t solve the problem. To determine wether it�s the PCB, the component or the process I would take a bare board, a component ( and maybe a different

I have seen an issue that escapes our ICT and functional testing or operates in an intermitent fashion. The lead is slightly separated from the PCB with a fully formed solder joint behind it at the heel an toe. The joint apears to have started to tra

I have a proto-type PCB with a 48-Pin Fine Pitch TSOP (0.5mm pitch) with a dimension of 19mm L x 11.50mm W x 1.10 Thickness. They are at the bottomside of the PCB and I need to wave solder the board. There are 8 of them at the bottom side. Are they o

I am electronic hobbyist, which has made a prototype for electronic lock. On showing this to a company they become greatly interested. All the Smt for the prototype were placed manually on the prototype. I would like to set up a line without any huma

Daniel: In response to your questions: * Moisture level (wt%) that may cause delamination in PCB�s. - Certainly, it depends, but 100% moisture will not cause delamination of a PCB. [Now, heating that water is another question, isn�t it? ;-)] *

Hello, I have to design a PCB for which the customer have the following temperature requirements: -55degC to +85degC operating temp. -61degC to +125degC storage temp. My question is: does the FR4 material meet this conditions? Which are the parame
