For reflow soldering, you are correct ! The higher surface tension of the solder paste in nitrogen atmosphere can increase the number of solder bridges if the component or solder paste print is inaccurate. Another defect that might increase is tomb

We have problems of solder shorts while using DEK Infinity printers. Some of the manufacturing lines are configured ina way that the side (bottomside) of PCBs mostly with passive parts is screened first and then the otherside (topside) of the PCBs w

Hi Jeff, Sean is correct. Although ultrasonic technology will work in post-reflow de-fluxing applications, you will receive concerns regarding ultrasonic �damage� to wire bonded components. Much has been written to combat this belief but the conce

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
