The latest software packages and stopwatch will do the job but if your manager is anything like mine he wants to know straight away from the BOM. If you split the bom down between placement machines i.e. caps and resistors etc on chipshooter and ICs

From what I have seen some component terminal finished have a problem due to storage also. I have seen pure nickel finished turn black. I have seen silver barring finished have problems too. It all depends on how you chose your process, PCB plating,

Hi, We have a problem sometimes where our soltec oven will accept another PCB too soon after it's taken the last one, so the PCB will collide with the last PCB that just enter the oven, and knock half the components off one of the boards, and destro

We are also interested in this, but where can we find the dimensions? We have thouht about some kind of a guideline to simplify the way of how we do the "Matrix tray numbers" input to our fine pitch machine. We do a lot of prototype production and ev

The 740 and 760 basically have the same specs as far as component ranges: 0402-50mm components. The 760 is a bit more accurate and the vision system is better. The 740 was designed when BGA weren't really around and so it can barely vision center b

I've used an old version (maybe 7 or 8 years old) of GC-Place to convert gerber to centroid data. It is semi-automatic. If I remember correctly we'd start by selecting the pads for the largest components first. The software would find matching gro

Do not believe every thing your suppliers tell you, even a written cert does not guaranty compliance. We recently purchased a Niton XRF analyzer. The first day in use we found component�s that were made for us "RoHS" that were far from compliant. Peo

Q: If you do not use a selective wave pallet does this not leave the possibility of solder flowing up thru the Via's on the board? A: No. Your board house can cover your vias with solder resist. Your board house can plug the vias. You can cover t

Heat guns used improperly will definitely damage components. You must have a controlled heat gun that can be set to the max temp you want pb =215C max, Pbfree maybe 240C max. This heat gun must not be able to be adjusted or you must have total trus

Relays huh? I can tell you from previous experience that relays are not a good heat gun candidate. Did you check how long this part can withstand the 240? I do not know what the 4 setting is on a liester but it is probably well in excess of the 24
