Your oven no doubt compensated by reducing energy to your heaters so it might not be as bad as you think. I'd be more concerned about even heating than over heating. My opinion is that an out of calibration profiler result is better than no result

Tony, We have a splicing service that would enable you to take a reel of 1,000 to 5,000 components and splice it down onto reels of 100, 250, 500, etc. parts for use in production. The price is $10 per splice and there is a set-up charge of $100 but

I once worked at a small CM that did this. On the floor we would save the spent tape to be re-used, so the only recurring costs would be the cover tape. Unless it was otherwise damaged the carrier tape was good for a few passes at least. It just h

Hey that was me way back! Anyways, use Dow 3140 (self leveling) or Dow 3145 (peanut butter consistency) and call it a day. No out gassing/acidic properties. 3140 also contains a UV tracer for black light inspection. Any tall caps should be epoxied if

Hi, I have a PCB with a blown PMIC (power management integrated circuit) multi voltage regulator IC. The PCB is rather rare and I need to replace the PMIC, its footprint is 7mm X 7mm with 12 solder points per side. Unfortunately I can only solder th

Thanks for the spare change. Questions are good and I did miss one item. Process has 100% solder paste inspection with a 3D inspection machine that has very few false calls or accepts. Ramp to peak is less than 1.5C/sec. Profile looks good, solder

Larry, from my days of working for a Telecom. company, Bellcore standards (now Telcordia) was our BGA Void guideline. There was some verbiage in the guideline that accounted for allowable VOID VOLUME ...keep in mind, VOID AREA and volume are 2 diffe

I am planning on starting a SMT plant to obtain local orders to start with in an developing country. I would assume a stencil printer, couple of chipshooters, couple of pick and place machine, a reflow oven, ICT and a functional tester as the startin

Maybe what you could do is have the stencil contain a tightly spaced mesh or grid of openings over the ground plane areas that you need to be solder covered. Also, to help the solder flow out better, you might want to decrease the percentage of metal

I've never seen that message myself... an idea though.. if your IP3 has a 4400 vision card you'll have seperate LSO cards. The encoders plug directly into them. It could be related to the LSO cards. You could try swapping the LSO cards and see if th
