Has anyone had success utilizing the lifted lead/ height checker feature on a Mirtec MV-7L. We recently had two separate events where the machine did not detect a lifted lead using the ic/bridge inspector. The soldering results came back with out def

3W. Figure 8-84 shown evidence of heel bend wetting(but no written criteria mention about the solder fillet must present at the heel bend). It is acceptable if the minimum D(3W/75%L)extend from toe which is no evidence of solder fillet at heel bend?

We've got an auto fuse clip (a pair of tin/nickle spade type receptacles joined with a nylon bridge piece) giving us fits. The pins on this thing have a right angle profile (symmetrical "L" shape) and make great flux traps. No amount of tweaking pre

Hi Jose, J-lead are very sesitive to coplanarity, which is the major cause for the defect you described. Other posibility is that there is not enough solder paste ; J-lead need around 10% more solder past then L-lead, You have to consider the screen

Alloying lead does not affect its vapor temperature. As you and others mentioned, the vapor temperature is well out of the range of your processing temperatures. Some people concern themselves about potential health hazards of lead by thinking abou

Your 316L stainless steel pot will not contain lead-free solder, over the long term. We'd bet that our solder machine equipment manufacturer will "swap" you a lead-free solder compatable pot for your current pot.
