Neil, We currently use only visual inspection with a magnified lamp and actually brush the board after the wave process to help knock off any solder balls. You wanna use an ESD sensitive brush material. Camel hair is what we use. It works real wel

Thanks to everyone who posted! I did get the boards clean and it worked well I used AIMTERGE 520A about 5% in HOT water.. I soaked for 10 minutes used a brush(handscrubber type)to loosen the residue. For the fine pitch I used a fine bristled small

At this time we will be hand spraying acrylic, probably using spray cans until we decide on a spray gun or an air brush, and get one ordered. Our volume is too low to even consider an automated system. Our current requirement is on an item designed

Can I dip the populated board in flux and achieve good results? Also how easy is it to clean the flux off the board afterwards if it is waterbased? Do you simply brush the board with a damp brush or spray some remover on the board? I also have this q

I'm not that concerned about the solderability of the motor. Our customer is concerned about the outgassing of the conformal coat effecting the motor brushes. Silicone will break down into SiO2 and SiC will result from a spark between the brushes a

Pogo Contamination

Basically, Brushing the pogo pins with dry anti-static brush will help but, cleaning it using solvents is not that advisable because it only leaves some residue that will further cause contact problems. Looking at the picture it seems that the UUT's

Hi all, Another thing that I would like to discuss here is that I used to come across few reports that mention about the flux residue has great impact on the PCBA impedance, especially when everything become smaller and smaller...I mean, when mother

Our production runs normally are 20 piece builds. We don't what to brush because of the brush marks left behind. Reason we wanted a machine is more control then dipping with a tub and modified paper clips. The other problem we have is the company as
