Serious question here, why do all the Lead Free Chinese Wave Soldering machines I have seen come in set at 5 Degrees angle - It doesn't work and bridges all over the place until th eangle is changeds. Are you guys finding this? Thanks Greg York

CK, If the contact length with the wave is decreasing when decreasing the conveyer speed and visa versa you need to check the machines electrical or electronics something is very wrong. Contact length is determent by wave design, wave height, convey

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

| I am building a board with T1/34 LED's in a 10X10 array there are 12 arrays in a panel. The LED's are body to body in the array, .1 spaced. The LEDS have been autoinserted on a Universal RAD III, so they are cut and clinched. The trouble I am havin

Hi, I will focus on the flux one more time. Try different amount(usually more flux should give you better result). Also depends what kind of flux you are using? Water based or alchohol based? Try with another type that you are using. Check the spee

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are

While not familiar with the flux, I'd increase the conveyor angle in a New York Minute.

CK: If you�ve done everything under the sun process-wise at the wave: different fluxes, more heat, less heat, more contact time, and less contact time; and are running out of ideas; let me table some thoughts. � "Don�t mess with Mother Nature."

Outstanding advice gentlemen! To borrow Dave F's line "I'd like to take a bit of a different angle." Ie. a few wave solder specific issues If this assembly is going over wave solder then avoid vias under passive components, it invites solder bal
