Check out PCT Automation Sysems Wayne | 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 com

Dedicated tooling uses what MPM calls an "H" tower. You mount the board support plate (dedicated tooling) on top of the H tower. If boards are only single-sided SMT, meaning only components on one side, the board support plate is flat with vacuum hol

Grant, Again, just my .02 worth. I would have to agree with Greg as well. Two Flex machines from the same vendor will give you much better line balancing, and I think better overall capability than adding a different type of 'animal' chip shooter

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

I need to know the advantages or disavantages of a plastic or FR4/Flex based BGA over the ceramic based BGA. We have a BGA package we are going to have produced. Some want to have it made out of ceramic because they feel a ceramic package will be a

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
