Does any body know how to change the inner width limit on a P-98 BTU oven? The inner limit is 6 inches, but I need it to be about 1.5 inches. Do you have to have a factory service disk from BTU to gain access to the limit. If so, does anyone have

Hi Peter, Out of the 1.5 billion components we shipped last year, we had 3 components back for solderability issues. All 3 had been taken out of their vacuum packaging and left to oxidize for a number of weeks. We don't see it as an issue, but we

* Try 1.5C / sec from RT to 165C * Hot soak at 165-175C for up to 2 minutes (I'd start with 60 seconds flat soak.) * 60-90 seconds TAL (I's start with 60) * 230-240C Peak. Thanks, Mario

James, We have 3 750's that are 5-8 yrs old. Never any major issues. Juki's service and support are the best. We bought a 2060 1 year ago and have been pleased with it. We placed a 20 mil pitch QFP with a spec of +/- 0.003" to test the machine.

CK You keep forgetting to factor in time. The "lots of juice" is say 3 times as much but it's for 1/5 as long. And you are wrong about the AC part as well. Do you also believe that warm water freezes faster than cold water? I saw that presented on T

Morning all, I have been tasked with finding a semi automatic placer for our engineering dept to run 1-5 piece prototypes on. Vision capabilities are necessary. Can anyone help steer me in the right direction for this... Nothing exotic would be place

As part of the IPC-4552 specification testing, they ran ENIG at 2 uinches for 1.5 million cycles for a membrane-type keypad application [there was no testing for the wiping-type switches]. They stopped testing when the membrane began breaking down. T

I am a doer myself but with the turn around and cost on EFORM stencils I prefer to be right and starting with math is always the best way. We have played with reducing apertures even stencil thickness as low as 4 mil. On the side that this component
