Snaggie Oxidized nickel is very tough to solder. Using the typical fluxes that are in everyone's fireproof storage cabinet [that they've been sampled by very nice saletypes] is like bringing a knife to a gun fight. Recognize that the flux you want

Hi all, Firstly, Wishing everyone a happy new year and a successful transition to RoHS (exempt entities please disregard the later part :-)) I am looking for a formal training institute/organization to train my operating personnel for lead-free hand

MSK As GS told you in an earlier posting, J-STD-002 and IEC 68-2-69 describe methods and equipment for component solderability testing. Go get a copy of either one. The primary component solderability test methods are: * Dip and look method * Wett

Hi, The ROHS compliant parts are usually Matte Tin on the outer terminal plating. There are also 2 further types of metal on the average chip cap - the undercoat metal of the outer electrode & the inner electrode. These are usually the same & are

I can't see why it would be any different, You are melting the balls into reflow to the pad. In my opinion, paste is only useful in this situation to keep the part on the board during placement along with some planarity concerns in some instances.

Hey guys - our lab has some data and photographs available for the MS2 for use in wave solder from some of the studies we have performed for P Kay. There are other versions being studied, but that is the only version available to market currently.

Let me give some information on the use of MS2. The average wave solder machine will use one liter per five day week per 8 hour shift. The usage can vary + or - 20%. Instead of removing 6 to 10 Lbs of dross every 3 hours you will have to remove 100 M

We have a great deal of new reliability data and we are preparing a full document that shows the statistically valid reduction in solder related defects as well as the improved throughput. It will include all of the SIR test results which are all goo

Amol, RoHS does not apply to BGA on their own. Depends where they go in ? DVD player vs server board There is "solder exemption" for certain product applications. SnPb ball BGA can used with tin-lead solder on server/infrastructure/switch telecom
