Chipbonder is best applied with a stencil. Too bad on the dispenser purchase. Little hint, use a Kapton Stencil. You can have them laser cut and can get them as thick as you want. Another advantage is the ability to make shapes etc for cleaning

This question is like asking what kind of boat should you buy. Depends on what you do with it.... I would ditto the CP40. Good discrete placer and very reliable. Your PCB Design, Stencil, Reflow Oven and Paste selected are just as critical to you

We have a customer who is going to be using the new Snapshot process. Has anyone used this process all ready. Who did you use to make the tooling etc. Was there any problems that arose during this process. The process involves screening balls into s

Hi I am pretty sure it isn't the pad that is causing the problem. To me it seems like those via holes through the pcb either to an internal plane or to the other side. I can imagine creating an interesting stencil to accomodate the vias yet you are
