Mydata (recently changed name to Micronic) will be more expensive than Manncorp but from my experience using Mydata, they are well worth the money. Tech support (in the USA at least) is very good if you go through them to buy the machines. You can

You are correct about the Manncorp machine, it was an MDC machine. The Essemtec machine is old(ish) but still runs fine, and last I knew they were still supporting it. My recent problem with Essemtec was in regards to software. I found a bug and sim

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

Good morning everyone! I'm searching through tech sheets and equipment manuals to determine the recommended paste thickness on the stencil during operation. We use a MPM momentum screen printer using SAC305 paste. Board isn't too complex; one QFP, co

I purchased the JW-3040 manual printer after seeing this company here. They were advertising the JW-3040 as new but their website said they specialize in used products. I specifically asked and was assured that the printer is new and comes with a squ

With a melting point of roughly 300°C, you would need to have the product see temperatures peaking around 325°C at a minimum. (I would make sure the components and PCB materials can withstand these temperatures) Most convection ovens do not go over 3
