Dear all: We had a severe curvature in our boards after wave soldering.Could a second pass in the wavesolder m/c reduce this curvature. If not then what do you recommend to solve this problem. Also how it can be avoided. Best Regards Hany

Dear all : We are suffering a severe curvature in our boards when coming out of the wave solder m/c. An Engineer suggested to enter them again for a second pass in the m/c expecting board were thermally mistreated just after the W.S. Can this real

Hello there: Could anyone help: 1- In a double wave wave solder M/C, is possible to completely eliminate the second wave without affecting the quality of the solder joints? 2-From a quality control prespective, what is the minimum accepted length of

Yep. What I'm really looking for is the minimum radius of curvature for 63/37, which is a function of it's surface tension. It's physical properties issue, not an agency issue. I've seen some references that I have interpreted to mean that it's some

Hany: In response to your questions: 1- In a double wave solder M/C, is possible to completely eliminate the second wave without affecting the quality of the solder joints? Many w/s machines have a turbulent wave and a smooth wave. The turbule
