| Can anyone pls email me a typical temperature profile for wave soldering process. | | Thank you vey much. | | rdgs... | Typical depends on the processes you're developing. Key factors in my experience are flux type and requirements, component

Several of our customers use our Summit series equipment for this purpose. Our rework stations are used in proto labs to prove manufacturability. Consider it a low volume, semiautomatic pick and place and selective soldering reflow oven. Some low

We are just starting to manufacture a PCB with a .039" fine-line PBGA. We are currently seeing voids, mainly in the center, that are as much as 45%. We also intermittently see the corner balls of the PBGA smaller than the center balls. We are using a

Dear C.K We are routinely wave soldering 0603 and sot23 on subcontract, hence we get what we are given!!. Being UK based we use a Blundell cms 400 dual wave soldering machine (made in Coventry), Tecan Stencils and Loctite 3612 adhesive. You must k

Earl said, in essence: | Justin is absolutely right ... | | Again, Entek is not much more than a flux coating ... | | Metallic coatings protect best, as we all know - especially those electroplated. Those coatings chemical come in next to no coati

| | Do solders exist that are both lead-free and low-temperature (e.g. 100-170 Celsius range)? If so, who supplies these materials? Any websites or contact information would be most helpful. | | | | Also, I am not an expert on soldering, so any
