check your de-panelling process if you are using break-out tabs or V scoring.

I'm looking for some design paramters for perforated tabs. These are the tabs that connect the circuit board to the break-away pannel material. I've never used these before, but I've seen some that have reportedly worked well. These tabs are ident

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

Has anyone use both methods of depaneling on PCB breaktabs? meaning v-score at the edge of the pcb and mouse bites on the opposite side of the tab (break out panel)? Thanks

Thanks Dave for the reply. I understand there is + and - to each process. We have been doing v-score for a long time and for the most part it has work for us. As PCAs become more dense and components are squeezed to use most of the PCB space, it now

we have looked into a number of depaneling machines and can't justify the cost. what we are trying to do is to eliminate failures due to part stress when employees are breaking out the boards by hand. I heard about pneumatic scissors one day but to

Hi Randy, From a bare board manufacturers stand point, scoring is probably faster and easier but has limitations. If your boards are square or rectangle scoring will work fine. Once assembled the scored grooves can be sliced apart using what is some

While I don't understand why, this topic comes-up fairly often on SMTnet. [That the topic recurs indicates there truely is a problem and I'm just too doopy to understand it.] Several things: 1 Check the fine SMTnet Archives. 2 Some glue suppliers kn

Check with your board house and see if they can do jump-scoring. I haven't dealt with a fab house yet that could, though, so, while it should be do-able, it doesn't appear to be super common, IMO. Alternatively, you could sand the edges after break

Have experienced this on a few different cap. parts. Agree with other postings. Following are solutions to problems we have had: 1) Cracked cap too close to board edge per IPC spec. Designer replaced part with 3 caps in series to eleviate stress
