I have another question: Does the slope of the conveyor is an important parameter in the solder joint quality? What is the standard in degree? Does that parameter can resolve my problem of partial fulling hole (between 50 and 75%)?

If you don't have Plated through holes you will not get any hole fill! There is nothing for the solder to wet to. Problem solved? Russ

PR, are you using the Indium or the Alpha Flux, I couldn't tell by your response. Russ

What thickness is required to process a double sided board with white tin? Is there an IPC standard? If rework is necessary, what is required?

Hi Greg, Is anyone logging the errors at QC/touch up stage so they can feed them straight back to SMT and fix them? (i.e. skipped components, poor paste coverage etc) Obviously the faster you spot an error the cheaper it will be for you. Cheers,

Hi, Actually, we want to run a benchtest for solder paste to verify if the paste we use is one of the best. So, with your experiments and tests, what's the top 5 for No-clean solder paste? * I mean leaded solder paste ( for the moment) :)

Russ, are you using any reduction on your stencil aperatures? How much for what type of parts? We seem to have to many problems with resistor network aperatures clogging. How well does this paste release from small aperatures?

I like Alpha Metals OM-5100. Very long stencil life with good results. Jerry

we use SENJU M705. type3 solder paste. Has a good shelf life.

But our requirement is that the conditioning unit has to be kept at a distance from the sensor. Is there any compensation circuit available to reduce the noise effect?
