Phil is wrong. In the real world, we know that part mfgers have not changed every one of their parts to make them "high temp". They just changed the plating. Anyone who thinks otherwise, has never run a profile or touched a warm board coming out o

We agree with Paul. If you prepare the components differently, so that they snap into place, you do not need to trim after wave. Most rotary trimmers put a HUGE amount of stress on solder connections, potentially cracking the connections. Some of

John: What�s the matter? Free gold � good thing for you, bad thing for your supplier. :^) Pre-tinning of gold plated leads is important to: � Prevent gold embrittlement of the solder joint � Determine if the leads are solderable prior to assembly (

Charlie, Check: a)That your wave is not too high/powerful as this will push up components due to force exerted by mass of solder b)That your conveyor is set at optimimu height so that a) is not required. If conveyor is too high, then the wave will

Ok, here's why we preheat. In my limited experience at our facility I have found that preheating the pallets a half hour before running boards thru the wave helps create a better gasket. We were having problems where the first boards run with the p
