Once you have selected your plating based on electrical and physical requirments, you should know that there is an inexpensive plastic storage packaging developed by Lucent which can keep any platings solderability from degrading for up to 10 years o

Hi, There are many companies shifting lead free solder wave. My question is can anyone give me idea if we can still use our old solder wave machine for lead free eventhough the solder pot is stainless steel 316L? Our solder bath has titanium nozzl

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.

Hi, I think that the time depends on the type of stainless steel, temperature and solder alloy. For example, one of our machines is delivered with 316 stainless pot and alloy SnNi. It worked six months (120days*16hours = 1920hours) and aft

Proy, Another issue is what exact formulation of SAC is used. Much of the SAC305 being used in Asia contains phosphorus, which is added in an attempt to reduce the heavy drossing that SAC305 produces. Phosphorus acts as a flux on steel so will increa

JD There are many lead free wave machines out in the market today. They promised to give best result for lead free. Companies here in our country who bought lead free wave machines 3 years ago is now having difficulties in controlling there machines

Hi could be relaited to the thermal mass of the screw/bolt. if there is no intermatalic formed and the solder just picks off id say this is likely. the hot wave hits the cold screw and cools the solder enought to leave some behind??

We are currently wave soldering connectors that are held in place by stainless steel screws. About 20% of these screws emerge from the process with varying quantities of solder attached to them. We have just had our solder bath checked and no impurit

A highly activated flux will allow intermetallics to form, because the hydrogen halide gas that formes at operating temperature will react with the refractory nickel oxide. Refractory nickel oxide is what makes SS "stainless". This will be worse wit
