Solder paste flux is main contributor, Lead termination chemical-oxide by products and PCB Plating-Chemicals. Reflow profile would have very limited if not no impact really unless is way off. Paste volume control and Stencil design plays a big part

Contributors in order of importance: 1. PCB design - if you have large thermal pads, a grid of via holes should be created. Components with low profile will not let the gas to escape from the joint. The only way is going down. 2. Reduce paste volum

First of all, I am not familiar with the machine you stated. But there is something you should check out. That is if the nozzle tips having solder paste stick to it or not. If nozzle tips having a fresh paste stick to it, the component might not a

You would have to do some extensive testing to really now for sure how much better coated blades perform than OEM blades. Deciding whether or not they last longer is just a function of regular inspections under a scope and accounting for the number

Interesting, I've not had a hands on with either Hawkeye or Ppeedprint SPI, however I was under the impression that speedprint printers give you an awful lot of printer for your money, comparing quite favorably with Asian brands with strong feature s

Hi Spoiltforchoice, it depends on what you pay for the printers new, but last time I looked there wasn't much difference in price between the DEKs and the Speedprint if you were buying multiple units. Remember there is huge markups on SMT kit. From

The price increase of electronic components such as MLCC has not stopped. In recent years, driven by the development of electric vehicles, industrial control and other industries, the demand for MLCC products has increased rapidly. However, the overa

Thanks to @davef and @Evtimov for trying to help. It's useful but not exactly the answers I would like to get. I'm going to reformulate my question. I'm writing in mm so that it's more precise: I have a 0.12mm-thick stencil for some 0.4mm-pitch QFN
