Hi, I think your friend wrongly changed the D code so that the finger width doesn't meet your requirements. And the fingers have long and short ones, which is hard to do selective gold plating because of not easy to add plating wires. Of course, you

Create a package, set the mechanical centering to the dimensions of the 8-DFN that you're trying to place, test the centering. Tweak the dimension that's failing. Shouldn't be too much of a problem. An 8-DFN package is nothing more than a rectangu

HI Tsvetan, Can you tell me what material your stencil was fabbed from? I have seen (from different suppliers) references to at least 3 different grain sizes of stainless for laser cut, plus electroformed nickel for laser cut, electroformed nickel,

The material is 0.12mm stainless steel, electropolished it's thick for fine pitch but we have lot of other big components on the board which do not solder good if we use 0.1mm thickness stencil. The 0.3 mm apretures are big enough and have good rele

Hi, I need the RF 800 Flux Acid titration procedure and also require EPT of the same to add thinner ( RF 800 additive), i.e we are using the flux rf 800 for our wave soldering process having foam fluxer , after 2 hours we are taking sample from the

Yageo announced their decision to stop marking SMD resistors back in 2013, and since then we have started to see 0603's that aren't marked, but larger sizes - so far - are still showing a value. 0402's have never been marked, and I doubt they ever w

I think you needed an IPC Class 3 annular ring because for very dense designs, the smaller the annular ring the better, as less space is taken by the pad or via and more space can be dedicated to routing the traces in highly populated areas of the bo

we are turning on the printer, suddenly the printer is off after checking there is solderball on pad capacitor component 0603 our question is what can a solderball stuck on one pad can when melting and causing shortsolder (being connected with other

Not sure you will find what you are looking for. Everyone is talking about converting the program but I think they are just talking about the x-y information. The problem is in the part/package data. Different Machines require different information,

Hi, You have 2 options: 1. You can pay for a software solutions but it can't do 100% work. You will complete manually a conversion (between 5%-50% based on a complex of your board, type of component and other problems). 2. Do it by your self using E
