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

We are having mid chip solder balls on chips and resistors. Seeing the problem on 80% of the assemblies we run. Anywhere from 1 to six of the balls per board. We have slowed the oven down, increased the pressure on the screenprinter to get less paste

Hi Jerry, normal proces would be; 1st. reflow side (top) 2nd. curring side (bottom) 3rd. insert 4th. solderwave Reason for this is that you have a better handling and no overdue stress to components in case you do bottom before top. It is also eas

Hi there, I'm actually facing a lot of trouble with PCB's presenting up to 3mm of bow /twist at reception i.e. before assembly. The PCB size is 220 by 230mm. The boards are to be assembeled SMD double sides with 05.mm pitch on both sides. In order to

Screening adhesive can be messy but is alot quicker than using a glue machine as long as you setupyour stencil machine either manual or machine, we also use steel stencils with a stainless squeegee but you can use a rubber squeegee not sure about pre

Is anyone out there successfully screen-printing SMD adhesive on an 0402 layout? We have successfully done 0603 and larger, but the deposition consistency on the 0402's is just not there. We don't always get enough epoxy on the board. We have tried a
