We're getting new SMT equipment! A flex machine and conveyors to boot. We have Simplimatic equipment now but I'm wondering about Lynx (I have the strong impression that Philips wants to deal) or this D-pace company? What's the 411 on these guys? Equ

In our continued search for another flex machine, we reconsidered Philips Emerald (low Vol/high mix Mfg). We already have a CSM so it makes a little sense. Then the salesman started talking about the Topaz. The Topaz supposedly is "practically the sa

The diode doesn�t appear completely broken. It takes a bit white color (cristal break, I think), instead of the normal red/orange. It works like a 20K-200K ohm resistor. !The diode can be working properly and sometimes change to bad! I think it may

Hello, We are using FR-2 in boards 15x10cm size, with SMD and thru hole components (about 100 SMD and 50 thru hole). We have some "rare" problems (flex cracks or caps, diodes, and so on). Would we improve something by using CEM-1 instead of FR-2?? Mo

We are assembling SMD-Leds (Chip LED cl-220yg-c-ts)on flex foil with Electrical conductive glue (Matthey A1401). When we investigated these foils we found cracks between the conductive adhesive and round the edge of the Chip-leds. This cracks cause f

I agree, that is not a gullwing lead in the normal sense but that doesn't address the failure. The wetting looks fine unless there is a problem under the lead, which is hard to tell since there is an obvious fracture. That appears to be the edge o

I'm requesting assistance in developing detection and containment methods for an issue with an SMD ceramic resonator (Murata CSTCE-G-A family). The returns have external visual cracks that originate at the termination and run at approximately a 45 d
