One thing that has to be considered when using rheometric pumps is that the board support should match as that of the pump head being used. You can print 6" boards, but you should really still use board supports upto 16". As mentioned previously if t

Dear All, I would like to take your opinion about the result that we have faced after cleaning the PC assemblies in a cleaning machine (Miele Dishwasher) with the cleaning detergent Qualitek Everkleen 1005. We use DI water for cleaning purpose in t

Hi all, Is it normal for some of the small nozzles to be rejected by the wide view camera? Every time I do a nozzle centering the narrow view camera shows green circles for nozzles 1,2,3,4. The larger ones (5 and 6) show the asterisk. The wide view c

Amen to that Patrick. I am from a traditional Engineering background myself - they never taught wave solder in school. My curriculum was mostly theory and labs. When I got out, I read all the soldering books available at the time and also watched s
