Just for the sake of passing along the information, the fine grained stencil provided zero improvement over the standard PhD stainless and was not nearly as helpful as the baked-on nano-coating. We probably won't be trying that again unless we go und

Hi, we are experiencing insufficient solder and bridging solder. Any recommendation on the inner pad (LGA) and stencil thickness. Any suggestion will be very helpful. link: http://www.latticesemi.com/~/media/LatticeSemi/Documents/ApplicationNotes/

Hello. We have a problem with QFN type. Component is elevated. Stencils are reduced. Vias is without holes. What are the solutions to fix the fault. Look at the photo. Attachment: https://drive.google.com/open?id=1OIgaXUz2yoKP3fWZg2rUsrmZMBWidk6_

Some things to look into are the component finish, material and composition of the solder, design of the smt stencil, reflow profile or process atmosphere (N2 or air)also contribute to the solder result. The influence of the PCB itself should be co

I just saw an ad for a Yamaha IPULSE M20 SMT placement machine. Is there any other manufacturer doing this? I like removing unnecessary steps from my production line. Here is a youtube video: https://www.youtube.com/watch?v=CfwBulvV0i8

We have used DEK for over 12 years, can remember only a handful of times they mis cut a stencil and have always stood up and replaced at no charge with no argument. Have missed their "same day" shipping a bit of late, but overall we're very satisfied

The way to determine correct pressure (in my experience) is to start out at what you would consider to be a low sq. pressure setting. You are looking for it to leave a slight film of paste on the stencil. Start increasing pressure in small incremen

Rehm Thermal Systems (Germany)offer in process vacuum reflow in convection ovens and vapor phase pending what makes sense - volumes of PCB per hour needed. There are other vendors getting into this of course. Can only get single digit void free join
