The is a serious concern of lead contamination of leadfree solder connections. For background, search the fine SMTnet Archives. For instance: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=30307

we are encountering a problem on our production. after dipping a copper wire AWG#30 to a leadfree solder the wire becom thinner and easily to break. does the leadfree soler has the capability to weaken the wire (lessen the diameter)after dipping to l

Anyone can help me what kind of solder lead use to connect thermocouple wire to pcb for profiling? We use ordinary lead on our profiling and it flats on when reaching 230C temperature. Our required maximum temp is 240C.

Copper wire will become thinner when dipped in tin/lead or lead free solder. The copper is disolved off of the bulk wire. This is one reason rework on solder pots must be restricted. Eventually, after repeated cycles you will have smaller and sma

Carl, You can use a high temp solder to connect your T/C's but we use Kapton or glass tape so the T/C's can be reused. Mac

Thank you mac. May I know what t/C's your using? Do you have any recommended High temp solder that we can buy? We already use Kapton, but it affects the curved on our profile data.

Kester makes a thermocouple solder: Alloy SN10PB88AG2 Flux "44" Core 58 Diam 0.031" I have used this to solder thermocouples to pcbs when profiling for lead-free temperatures. When done you can unsolder the thermocouple and reuse it again. This g

arnold: I did not say that Sn100 dissolved copper faster. The graph of dissolution rates [from the link above] shows that Sn100 dissolves copper slower than many of the other solders.
