If you are using a Humiseal. try UV-40 gel which is about 20Kcps. it will dam your material from capillary flow. It should be applied prior to coating of your low viscous material.

SM482 has 6 heads and can place parts from 0603 metric (0201 inch) to 55x55 mm with ISO benchmark 28Kcps

Hege, can you share more info on the formulation you ended up using for the micro dot dispensing? I'm trying to find the proper metal load and viscosity for the auger valve dispenser that we are developing and it looks like the regular low viscosity

Hi, We are in the process of evaluate our solder paste,incoming inspection over the solder paste, stencil requirments: 1- Is anybody using/requiring 1000 Kcps or more on viscosity to your solder paste provider ? Why ?? 2- Is anybody using step stenc

Hi, I got an interesting result after completing DOE that more open defects occurred higher the viscosity.The ppm would be 500 while the viscosity is 950 and it would be 1500 while the viscosity is 1050.The range of viscosity is 900 ~ 1100kcps. The p

Hi, We are in the way to evaluate different solder pastes, improve our solder paste incoming inspection steps, re-define our stencil requirements and the following questions are open. Two questions, 1- Is anybody using/requiring 1000 Kcps or more

60-70% RH will be a challenge if you are running a water wash solder paste (and could be the reason you are seeing the problems). If you are running a no-clean, humidity should not be an issue. As long as the profile looks OK, I don't think the con

Currently we are having a lot of solder balls, after a few hours of continous production. This is how we work: load new solder paste at the beginning of the shift, less than 500grms. Then, the operator loads new solder paste periodically, every 3 to

Flux: No-clean pastes tend to have a wider print process window in terms of print speed and pressure. More importantly, no-clean pastes are more tolerant to changes in temperature and humidity. They also exhibit longer stencil life than water-solub
