Hello Steve: I work at Navico, a company that makes GPSs and Sonars among other products for recreational fishing. I want to know if our SMT, Thru-Hole and Final Assembly areas need to be in a cleanroom environment? I've worked in another companies

We are using an inline aqueous washer with saponifier to clean smt assemblies with rosin based no-clean solder paste. Looking for a reliable, cost-effective way to monitor the cleanliness of the assemblies after cleaning. Any recommendations?

we will be using water soluble solder paste. cleaning will be for smt assemblies only. waste water will be treated prior to disposal. as far as testing for cleanliness, any suggestions or recommendations on test equipment would be greatly appreciated

Third, if component placement is off, fix the machine (i.e. calibrate, check cleanliness of lenses and sensors, damaged nozzle) and not the CAD locations.

We've configured SMT and Wave lines such that each line can run either No-Clean and Water soluble process. As we are doing cleanliness study, an observation is there may be cross contamination when we share the Rework benches or PCB trays between No-

IPC-J-STD-001E in regards to Ionic Cleanliness standards states less than 1.56 µg/cm² of total NaCL. Assuming a typical electronic process which involves smt, wave, and post-hand soldering and uses NO-Clean flux throughout all process, is it typi

A certain degree of cleanliness is needed in SMT manufacturing environment but not as overkill as place it in a "clean room" environment... Yes, dust could cause defect on PCBAs (and there are research papers about it too) but onl

We are trying to establish requirements and process controls for completed, cleaned SMT assemblies. We have problems with our high impedance circuits (100 meg ohms) being affected by residue. Some boards require additional cleaning cycles to remove
