I work in a plant located in Monterrey Mexico, I would like to know where I can sent some boards to be analized since we have the suspect to have a black pad problem with the boards. Any Idea?

Mydata is worth looking at. I think they are a great first machine. And it's best to buy a used one direct from Mydata. They are extremely anal about their used machines and you might not be able to tell it's a used machine, it will be refurbed so we

Contact your solder paste manufacturer and get the reflow profile recommended for that particular paste. Then, duplicate that reflow profile on your oven. You will need to use thermocouples. You may have to tweak this profile a little. | We use no

Hi All.. I need your advice, when you send your boards to be analized by external lab, what kind of result would you expect from them? Do you expect them to find the root cause of the problem and give countermeasure of the problem? (this is what I e
