Hola I have this connector (atached image) for Wave Solder process, there is one pin with no solder on the top, for me it seems that the large trace connected to that pin is "stealing" the heat... I'm not WS expert... can it be corrected by profile?

You might consider to contact a lab to Run a microindenter against a know good soft gold sample. The knoop value for the soft gold will be much lower than for hard gold. This would be reflected in the diameter measurement of the indented samples.Smal

SMTnet colleagues, I am looking for your opinions on the PCB/CCA cleaning process. Regardless of fluxes or population complexity I want your opinion on these three cleaning processes and what you consider to be the best for what and why. Thanks for

I am sick of Kapton. We have varying levels of leftover residues on multiple brands and I'm done chasing this thing. We have tested some wave tapes that were total garbage in years past. Really don't want to go there. Peelable liquid masks - Who

Techspray has a broad line of peelable solder masks. We use the Wondermask P for masking conformal coating as well. Call the company or rep to determine which product is best for you. I am not affiliated with Techspray in any way. If you get tired o

We have a YesTech YTV 2000. I'm being asked to set up a program to test the destination solder on through hole parts to make sure there is a lead in the hole and there is solder in the hole. If possible I need to test for bridging also. This is being

They're hand placed and hand trimmed so they may be straight, may not be. And the solder (I think because its lead free) is a dull grey color to there is no reflection from any of it. The solder, lead, and board all show as a dark grey color under re

By "dark grey color" do you mean with the histogram? Red or black maybe, but grey? Are you using a color camera? Can you use a reverse image? Does a bare unsoldered joint appear bright or reflective under red lighting? You could look for a low wh

What type of filtering are you using? Your solder inspection should be using Histogram Inspection as the Decision and red filter for preprocess. Make sure your settings are correct and check your binarized image under Histogram setup. you should s
