| | Looking for a manual machine to de-panel with the panels held by 60mm tabs. Each panel hold multi-boards consisting of different shapes and sizes. Scoring is apparently not an option and volume does not dictate a large scale machine. | | | Try

We are currently looking for a way to measure pcb stress during our assembly process. We would like to get an idea of what amount of stress (flex) the boards are undergoing. We would also like to use this to compare a few different processes--for e

Hi everyone, Does anyone have experience and applications knowledge, to help recommend a singulation machine? for depanelization process of a : 1) 0.65mm thickness PCBA, with 0603/0402 SMD, 2) with materials composition makeup of a 1.5oz copper,

a leakage exists in the capacitor net (1206), which cause the voltage down so much. the process flow is: printing-placement-reflow-hand load-wave-depanel-FT. I find possible stress maybe exists in the depanel stage, does the extra stress cause the ca

We are building seven different assemblies that have flex circuitry that go off in four different directions within the panel. The panels are square to facilitate flow through smt & wave solder and depanilized in solder touchup. Currently, we are usi

Seen cap cracking before. It can be caused by thermal stress as noted above, but don't discount mechanical stress and handling. Your depanelization method is a strong candidate. We applied strain gages to baords and benchmarked various mechanical

Too fast heating/cooling rate in reflow (look at mfg's spec.). Z "overdrive" on pick and place or chipshooter though unlikely I would say. Depanelization method (bending a scored board to break it is tough on things). Bad PCB design - cap. too clo

Dear Tim. It is nice to meet you online. I am very glad to introduce one korean company producing various depanelling machine. This company has installed more than 100 units in NOKIA mobile phone line located at Masan in Korea. If you need more i

Yet another example of narrow focus. "What's the best and latest machine out there, and should I use a technology that's been around for decades." Wrong approach there, Chunks! Think outside the box. My firm, Worldtronics Consultancy Services, In

As R&D project leader I have worked at FICO on this issue the last years. Maybe you have found the info you are looking for but for laser cutting are more companies involved than the three you found, the experience I have with laser cutting for PCB p
