cn, Currently we have a DEK265GSX a DEK Infinity and a MPM UP3000 printers and previously had MPM Accuflex,MPM UP1500 and MPM AP24s. No advice for the UP3030. We always had to work on all of the MPM printers for one thing or another and every time we

I agree with Chunks. Programming was much simpler. The 2D inspection is much better on MPM. I didn't have to use offsets on the MPM or the DEK very often, but did more on teh DEK. I didn't like the front justified stencils on the DEK. I also did

It all has to do with charges being drained. IIRC the pink stuff won't build up a charge but doesn't drain it well. As for the need for mats, how are charges being drained now? I don't think you can have no charges building up. With ESD all you can

I still think the best bet is probably an SMT pre-bake operation to ensure that there is no moisture in the board. Vapor pressure is usually the leading cause for delamination, so removing the source should significantly help out. Unfortuantely, pr

Hi, I've had some trouble with one of my GSM cameras. Its a 1 mil camera (in circular housing). Some components have fallen down the gap between the glass cover and the LED array closest to the rails. One of the resistors (closest to the left) has b

Thanks guys! Very helpfull info. SWAG, the manufacturer states that this material can withstand up to 350 Celsius for a short time period (around 10-20 seconds). It is my understanding that Durostone absorbs heat very very slowly like ceramic thus

A little more detail on our application: It is a large fixture (approx. 15" x 18") that spans the chain fingers in the reflow. It has several cut-outs and reductions in thickness to allow for better heat distribution. It worked well/stayed flat fo

*We've tried the WSP80s for leadfree, also SAC. Problem with these was when they are not being used, they keep their temp and oxidate like hell. Second problem is as Russ states, the sensor is not in the tip, therefore to get the same heat in the t

Thoughts are: * Most board fabs have routers that can do this work. Can yours rework these boards? * Scrap the boards and start anew. Someone made a mistake. Cut your losses. * As a wild and crazy guy alternative, buy a router with a 45* bit from
