Breaking scored boards, breaking components.

We are leaving 12-18 thousands material when scoring. Several components are cracking during depanelization. The pizza cutter machines out there are either too expensive or too slow to solve our problem. I am looking for a magical solution. In case

We have recently purchased equipment that would probably solve your problem. We are using 1.6mm pcb material 1/3 of which is left unscored. When the pcb is de-panelized there is no damage to any components and we have cut our break time in half.

Brian, We recently investigated a depaneling press that might suit your application. The labor savings over pizza cutting will probably make it justifiable for you. The company seems to be lesser known in the US, but is partnered with a Japanese c

Oh boy, does that bring back memories!!!!! You are most likely breaking components when the board is flexed during separation. Any components perpendicular to the score are candidates for mechanical stress. We overcame the problem by making our ow

I have several reels of components I purchased from Chinese source. During pick and place, the tapes keep breaking (they tear diagonally along the reel). I notice the tape is very tight if I try to pull through manually. I tried several over 12mm fe

This may help you regarding the V-Groove or scored board designs. With respect to material left, I did some experiments and found that for our process .009 of material seemed to be ideal. There was minimal stress required to break the boards apart ye

Ok, help me out here guys and gals...... I have never understood the concept of scoring on mixed technology or SMT boards. It is quite obvious to me that the potential for SMT solder joint damage through the mechanical stresses of breakout are high.

Through hole headers in long strips Anybody know of a tool/manual punch and separate these instead of sidecutters very slow....

As I understand it, customized equipment for breaking the headers out can get fairly expensive. I've used two methods to do these, other than using cutters. First, we bought a bandsaw to use for cutting. The only disadvantage to using the bandsaw
