In the same way my BMW gets me to work and back, it is a much different class (pricewise)than a Toyota Camry, yet both accomplish the same goal. Every day. Is the BMW a "better" car? Is the Camry a lesser vehicle, even if it gets me to work on time

Sure you can use it it with leaded HASL. Recognize that ... * Your Sn42/Bi58 will no linger be Sn42/Bi58 * Your leaded HASL will no longer be the same leaded HASL that walked in the door to your plant * Lead from HASL coatings can diffuse through the

Ryan ... "As for bismuth-based lead-free alloys, a lower melting temperature than that of tin-lead is offered together with a cost similar to that of tin [in the area of $3/lb]. Unfortunately, bismuth in soldering alloys tends to create embrittlemen

Thanks Dave , my question is about Spopov want to try "Lead Free" SnBi (but uses it on Leaded finishes), but is worry about its low melting point (at this point, no longer 138 degrees as he wrote, but rather in an unknown and unpredictable range bet

My first attempt was similiar to that. It was a straight ground trace running past the circular pads that were recieving the shocks. It was hit and miss when the arcs would occur. When I cut notches in the trace so the ground line had a point next to

I'll try swaping cards and see if the problem follows the card. So far, my guess would be the motor going bad. I did change the brushes, X wagon cables and every cable that goes to the midas unit. But that didn't fix it. The problem is that to replac
