Good afternoon, Take my word, bent THT leads will surely cause problems with manual/automatic component insertion, and surely will create voids in solder joints. As a rule, PIH components are placed by hand and good PIH THT manual component placemen

Hi Bruce, We are a CM aswell and I can sympathise with your situation but you will have to advise the customer that you have issues with this board finish and recommend an alternative. If they are exempt why are they supplying you with Leadfree Boar

I'm looking for some information on soldering irons being used in my no-lead process. Specifically, my floor seem to be burning out tips at an alarming rate, when soldering lead-free assemblies. Today, I had one woman burn out a brand new tip in 4

The process that burnt the tips up yesterday was hand soldering/touch up of lead-free assemblies. Not even assembly, but just touching up boards that we've soldered on a solder pot...which will lead to another question. We're using SAC 305 WS482 3

ok, sorry ,750 was deg F and which I said 350~400 were deg C, I got a mistake. As I know, we use 660~720 deg F to do reworking for lead free solders such as SAC series and SnCu0.7 series solder to protect irons and components on boards. when temp.

I am looking for white papers or information on what happens to 63/37 solder paste alloys when overheated. I have had some solder joint analysis done regarding missing finish on some of the joints. The analysis came back showing a low lead content

We're not real clear on the issue. [Got ourselves wrapped around lead (Pb) versus lead (termination), we think.] That aside, comments are: * Boiling point of lead [Pb] is [/K]: 2022 [or 1749 �C (3180 �F)] * It's possible that the material that com

It sounds like something is a little off here. ROHS compatible and ROHS capable parts are going to be ok with a leaded solder paste and processing unless you are building high reliability product.( some are going to argue that even high rel products
