SMT-ypw: Does PWB supplier start to implement PWB drying packaging? B3: YES! The fabrication of the PCB involves a series of wet processing that requires counter-measures to remove moisure. While some of the PCB processes also include bake cycles th

Hi, I am setting up a Water Wash process. Can the Experts our there help me to understand the whole structure of the complete DI Plant setup to the Washer and back to the water waste treatment i.e. what filtering system needed in between, carbon/mix

Sort of accurate on the LT... It started off that way (earlieast machines had shuttered camera like a GS), but quickly became the same machine as a GSX. Had same cameras (black, them silver, then green) same screen cleaner options, same tooling optio

Dave is correct. Try http://www.ccrco.com Removal of conformal coatings from specific sites might be a more manual process. Think small abrasive cabinet, and an air wand shooting wheat chaff or a (softer) plastic bead media. For components with A

As the technology has changed towards surface mount, so has the applying adhesive. In the past clinching parts would have knocked off SMD parts, but no that has all changed. So applying the adhesive via screen print is common and any thru-hole part

We have been running double sided surface mount pcb assembly for several years with no adhesive needed. We paste, place and reflow one side, then repeat the process for the other side. With Rs, Cs and small to medium ICs we have no problem with par

On TH parts we have been hand soldering. This last summer we purchased a Rhythm selective solder machine from RPS automation. I did a factory tour of both RPS and ACE since both facilities are about 1/2 mile from each other. In comparing the 2 c

Oops...just noticed you were referring to wave soldering. We'd still suggest a water-soluble flux, instead of the no-clean; especially at wave soldering. Also, checking pre-heat temps, and dwell time on the pot. Is the wave a chipper wave? If not
