| Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a me

To all Techneters, Here�s a last chance to support the exempt request for lead in solders, Link to the publication and supporting documentation: http://tinyurl.com/y3p2dc Follow link below to support the exempt, John (RoHSUSA) made it very simpl

It's [maybe], because you melt [reflow] the itty, bitty solder pellets [that were formed from a liquid solder] in the solder paste. * Wave solder is melted solder bars [that were formed from a liquid solder], also, but someone named it wave soldering

Running a soldered BGA through a wave solder pot is very risky: * 230-240*C temperature of the pot could damage the device. * Solder in the pot will certainly cause bridging between BGA solder balls. * Solder in the pot could melt BGA solder balls.

Unlike components where the solder paste has been reflow soldered, wave soldered components have an "infinite" amount of solder available to make a solder connection. If you have good solder flow, pad and component termination size are going to be b

Electronic devices required higher speed, I/O capability, and density to meet standard requirements. Automated robotic soldering solutions that meet the demands of applications are too challenging for hand soldering. Manual soldering, even with the m

Platitudes about soldering are: * People ARE NOT good at soldering. * Machines ARE good at soldering. You can purchase a good used wave soldering machine for $20k. * Training helps people to be better at soldering. * Your solder connections should
