the copper forms intermetallics with tin to get Cu3Sn and Cu6Sn5. thus intermetallics formation consumes Cu and depends upon the cooling rate, faster the cooling rate, lesser the intermetallic formation

Slaine, our intuition is the same as yours [that 100Sn should dissolve the copper faster than other solders]. Bob Gilbert's FCT data shows otherwise. Look here: http://www.fctassembly.com/newsltr/2004/0804/Aug04.htm

Hello Arnold, Yes, by definition of joint formation, copper will dissolve in lead free solder in order to form the connecting intermetallic layer. There is a distinct difference in the copper dissolution rates of the major alloys being considered wi

Hello Arnold, Just to clarify the Sn100C discussion: Please note that SN100C is the Nihon Superior alloy composed of tin/.7copper/nickel. The key point in regard to SN100C is that Cu does not go directly into solution but first reacts to form an inte

Does anyone know 2-pin DIP components? Who uses them, why are they in the DIP form and not simple axial components? Are they usually placed by hand or by modified DIP placement machines? Thanks for any answers, Erhard

Anybody know where I might find a DIP surface mount I.C. to a DIP .10 inch feed thru adapter board munuf. or distributor ? Thankyou in advance. Doug K.

Reflow => Top side DIP => Bottom side glue => Bottom side SMT => Wave solder ... We couldn't keep the DIP clinch apparatus away from the bottom side SMT if we did the bottom side SMT prior to DIP.

what is the effect of pre-dip tank temp. and dip tank temp. on the thickness of the IAg?
