I would first check to see what the maximum temperature this operates at I remember seeing my first one on Ebay the other day and it is a small bench mounted machine. You need to ensure the solder bath will operate up to around 260 - 270C. ALL Lead F

We are experiencing delamination / measling on card we have been running for years. No change in process. Same equipment, profiles etc. The weird thing is we are experiencing it on pwbs from different mfgs and different processes (reflow, wave, selec

Board House, Thank you for the info. We are baking 6 hours at 250F prior to processing. We are a military contract house that has always baked and have never had issues until recently. I appreciate the info. We are sending a team on the road to visit

Hi Steve, first you have to decide if you need adhesive or you can go with solder. Usually depends on the TH parts. Otherwise dispensing is always more problematic process than print. I would go with the printer and stay away from troubles. It is f

Steve, We use stencils for applying adhesives to PCB's, with our DEK Proflow system. Works well for us. Once in a while, we have to manually add adhesive to a specific location depending on the component height. Vary rare though. You shouldn't have

We exclusively use a printer to do glue these days but keep in mind there are times when glue and paste work best. Things like poor layout (ie shadowing) or tall parts that may shadow themselves or a wave solder machine that is not particularly good

If you find the correct type of adhesive/needle size then dispensing certainly is no problem. With a footed needle a very repeatable process too. Much more flexible than stencil printing and no need to mess around with stencil cleaning. But with auge

Are there any good solutions for getting good barrel fill on PTH boards using Pb Free solder and No Clean flux. All of our boards are having issues getting minimum required fill per IPC. It does not matter if the board is 062 or thicker, any pin conn

on the front end in design, minimize the pth connections to ground planes. this takes alot of work by the pcb designer and the approval of the design engineer. connect maximum of 4 ground planes to pth, minimum 1 plane. use spoked connections. ev
