I never understood the statement "process indicator". The 7095 committee used that wording but didn't explain it. Other than really unusual cases such as champagne voiding, BGA voids are not a reliability issue. A half dozen studies have come to t

We have CP60 in the last 2 years, and CP63 1 year. You should check your local C/S about spare part stock, service support, and training for your employees. My conclusion about Samsung Techwin MC's is: cheap, and working well. But dont except too muc

We have a customer transitioning slowly to lead free due to necessity rather than a need to comply i.e. some of their BGAs can only be purchased Pb free only. So for this we would want to produce them a leadfree soldered PCB (not necessarly RoHS comp

You have 2 groups giving us 'evidence' here: 1. the research companies who will do anything to scare us, just to make sure more research will be done, if they said everting was fine they'ld be out of a job in a sec. Ex: look at that paper, a leaded

Ah, I have 3 of these ovens. Not bad ovens at all. You mentioned a PLCC 64. Is this part having the delta T problem? If so, that seems odd. Without knowing your exact set-points, you could pump in more heat up front. Change blower speeds to hig

Will the Pb part handle 240C? That is the first question that you need to answer. If it will then yes I would run the pbfree paste and profile. I assume that all other components are pbfree. If not, the same questions will need be asked as for th

Billy- I have some Mydata tools now, they are from another supplier. I am something of a perfectionest and these are not up to the quality standards of the nozzles that we make ourselves, but my supplier does replace his defective parts. If you have

Have a problem with Omniflo 5 (-97 vintage) pin chain conveyor. Occasionally the conveyor stops for a second or two, then makes a slight jerk, then stops again, makes a jerk etc. Then suddenly the problem goes away only to return next day (we switch

Hi Rob, They want you to think that their products are subtly different & that they are not interchangeable, although they are in nearly all cases (this is different for high frequency RF design). Also your layout guys aren't going to love you wi

We have this panel that is Gold Flash. Am I correct in assuming this is technically a lead-free panel then? We are running a WS paste, and the QFN28 has balls of solder instead of a fillet. My Max temp is 216, and the TAL was between 52-57 secs with
