If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

With DIP type components, a sub-par fluxing method (foaming a no-clean), and a chip wave where one is not needed are formulas for bridging and insufficient wetting. If you have SMD's on the wave solder side of the board greater than 0603, and no SOT

The main problem I am having is getting the Rising slope 1-3 degrees. If I slow the conveyor down then I have too long of a reflow and if I speed it up then my ramp rate is too high. I was not sure if I need my first zones at a low temp or higher t

Hi The temprature for the first zone should be more as the PCB entering the oven from the ambient shop floor temprature needs a higher temp.Next zone could be lower than the first zone.The ramp is a relation of conveyor speed and the temp profile.T

Some things to consider 1. can one operator keep up with manual operations and not slow the line down? If yes, great. If no you will need a way to allow more than one operator access to the next board coming down the line to not create a bottleneck.

Kevin You had stated "manual" so I assumed that you are looking for some better tools to actually do the work, but you wanted to keep it on the conveyor line which would require some workstation configuration to have the right tools at the operator

I would like to understand what different options people are using to place low volume / odd form parts. I am very familiar with the tweezers / vacuum pen method however this can be less than desirable. I am looking into a manual pick and place to

Water soluble pastes generally work best with a ramp-to-spike reflow profile. Check your paste manufacturer's recommended profile. There are many factors that impact your profile; board thickness, component density, buried thermal masses, board si

I was looking to swap a Universal GC60 from 240 to 400 V 3 phase. I can get a transformer though and just looked at prices and they are quite cheap. My 2 main options at the moment: Option a: 1 Universal Genesis (2006) some feeders + essemtec ove

Hi Evtimov 'hege gave you a plausible explanation for what's going on with solder running-up the lead of your components: TOO MUCH METAL!!! I've got different one. This explanation goes along the way that you're thinking, but just opposite. The rea
