Yes, it can evaporate. My point was manufacturers suggest cool storage to avoid seperation. I guess if the flux does seperate and get pushed to the top it could have a greater chance to evaporate. I have only seen such seperation on year + old jar

i would say that you are there already. with 10,000 DPM0 you have a 1% fallout, you are at 99.9 basically. 1 out of a 1000 boards will fail? of course one thing we need to know is how many opportunitites do you count for a chip resistor for exam

We're in the process of trying to select a rebuilt, refurbished, or well serviced flexible placer, something that's capable of placing in the neighborhood of 10k and up. We're a high mix low volume shop so easy setups is key. I'd be looking at a MY-9

Hello I atteneded the show as a supplier. Been to many over the years. All in all it was not too bad. The show layout was a bit differnt and not in exact grids as in past that made walking the show a bit interesting. They had buses running fro

We are looking at replacing our aging 4790 for something. We are replacing our GSM1 with an Advantis. We are a prototype shop and do runs of 5 to 30 normally and once in a while a run of 300. So we are looking for flexibility and ease of set up.

Immersion Silver, ImAg, is becoming the finish of preference. This is due to it having similar process limits vs. SnPb HASL. There were some early concerns about shelf life, but new chemistries have extended finish shelf life to 12 months+. Many boar

Whether there's a fillet or not depends on the component type. Most have a fillet but some, such as QFN's, don't necessarily have one. Have a look at IPC-610D Workmanship Standards to understand when you should expect one and when you shouldn't. T

You are probably using a GSM since you mentioned "enhanced board setup". 1.- Your CAD data. It works better when all your data uses bottom left of the PCB as a board origin ( BO ). If my CAD does not use bottom left as a BO, then I edit the data in

What does your customer want you to do? I would not want a CM soldering one of my boards with leadfree paste if I didn't ask him to. Whatever you do, get approval first. Two things to consider: If the other components are not rated for leadfree tem
