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.

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.

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.

Carl,

Try this link http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6929&#Message27727

Or search 'thermocouple attach' in the forum

Good luck,

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 gives you a more accurate reading than using Kapton tape for attaching the thermocouples.
