I just installed a new CCD in a 4.0 mil upward looking camera - GSM. It's working well but is slightly out of focus. Do I adjust focus by moving the lense in and out of the camera mount or do I use the ring that is actually part of the camera that

we do a similar thing but make the template from paper, we just print out an image from the gerbers (to size) showing both sides in different colours, we set this down on the table (had to work out first where the correct position was) then we place

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

The main cause of voids is your flux out-gassing during reflow. Try a little "knee" or slight soak in your thermal profile to dry out the volatiles a bit. Typical soak ranges from 130 deg. C to 170 deg. C for around 30-90 seconds.

All, We had a power cut the today. Machine times out on Actuators and Paste Dispenser hence it will not Initialise fully. I have traced back each related card but all seem to check out fine. Next step is PSU (looks awkward to access) Any ideas fe

Are your preheaters maxed out then? What is conveyor speed? anyway I would not have issue with that configuration at all. I have actually found that when using convection for some watersolubles you actually dry out flux and performance is worse.

here are my thoughts on kester, I have rec'd a sample to qualify here and we cannot even get it out of the cartridge it is so dryed out. Rep informed me that Kester has a problem with its chemistry right now. Product is Mfgr'd in off shore location

Well said. From my experience, the Chinese would ship out of spec. product knowing full well it does not meet the requirement. If we catch it, good for us . . . otherwise we are #@%$%#. The Japanese (and others) on the other hand would rather pull

I remember many moons ago seeing a refridgerator for storing solder paste which issued them out in a FIFO manner and had the option of a PC and bar code scanner for logging them in and out to the lines. I can't seem to find any trace of it on the net

Take your choice: * Can't image this is a good thing. The board under the die will 'dry-out' and turn brittle over-time. It's possible the way attachment glue bonds to the board will change as the board dries-out. * Epoxy suppliers pad their number
