Recently, our engineer Peter went to Thailand to provide after-sales support for our customer. In these days, we had installed a SC-900 selective coating line . Moreover, Peter gave patience and meticulous training to their staff, make sure they master the machine usage .Customer and agent are satisfied with our support and give their affirmation to us. SC-900 is a high Performance 4 axis Selective Coating Machine ,which is equipped with high precision servo control system , various valves , CCD system ,material tank weight detecting system etc, which can provide a high efficiency conformal coating process .The maximum coating size can reach 400mm*450mm with SC-900. So far, we've installed several dozen conformal coating line all over the world. It have excellent stability and performance. Check below link to get more info!

Tin-Silver-Copper alloys are the primary choice for lead-free SMT assembly. Although there are other options available such as alloys containing bismuth or indium and other elements, tin-silver-copper solders, also known as SAC alloys are by far the most popular. They are used by approximately 65% of users, as last surveyed by Soldertec in 2003.

The present work offers a discussion and a first case study to identify and illustrate voiding mechanisms for a particular TIM between a heat spreader and the back of a flip chip. Pronounced differences were observed between stencil printing and dispensing in terms of initial void formation, apparently related to the specific properties of the material. Measurements of the effects of heat ramp rate and peak temperature showed the subsequent evolution and final void size distribution to be determined by the initial part of the cure profile up to the material gelling temperature.

This paper discusses solder paste printing and flux dipping assembly processes for 0.4 and 0.5mm pitch lead-free WLCSPs and the corresponding assembly results and thermal cyclic reliability obtained. Variables evaluated include reflow ambient, paste type, and stencil design. Reliability is also compared to results for the same components assembled under identical conditions using SnPb solder.
