For us, it depends on product volume: * Low volume: Tailor's scissors sharpened for the job. * Mid volume: Custom die used in a press. * High volume: We don't do this, but we'd have buy a singulation machine, er something like that. [Search the SMTne

Have never heard of solderballs during rework using solder wire. Noticed the tendency to have little balls of flux with too hot iron and lots of solder used for shields or massive cables to be connected. Seems to me a question of believe if it does

JBC Tools has a wire solder feed solder iron. You can control how much is dispensed to the tip. I have sold several of these to customers soldering wires in to terminals. The hand piece is bigger than the typical solder iron but it beats the alter

Singh, The equipment varies in price. We make a wire bonder called the HW27U-H Wire Bonder. This is a gold to gold wire ball bonder. The substrate size you mention is within the area we can take into the machine. The key is the bonding area.

Electroplated nickel and electroplated gold is the more �traditional� finish for aluminum wire bonding. That surface was an extension of gold thermosonic wire bonding that requires a thick [50 thou min] gold surface. For years fabricators recommend

I have been reading a good deal about IMC (purple plague in particular) in gold wire/aluminum pad wire bonds. My company uses ultrasonic wedge bonding, and for the most part all of our bonding is gold/gold, however we have one particulr part that has

What you have run up against is the unfortunate consequence of the transition period from Sn-Pb to Pb-free. In the past 2-3 years there have been several studies highlighting the differences in reliability between mixed metal systems, Sn/Pb, and SAC

We recently had a discussion with customer's QM - he claims that calculations for a proper solder wire diameter and soldering iron tip size (and temperature) have to be performed and documented for all manual (T/H) solderings (based on component size

What kind of volume and what kind of complexity? I know a few lead wire houses that are low cost and do a good job. We do a lot of cables. We dont do harnesses. Most of this type of work has gone to Mexico. Give me a better idea of your requirements
