A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect

In theory, no clean flux residues are electrically benign...period. Here's a good test. Subject the board to some moisture/humidity, and have your circuit designer ohm-out any areas that may be affected by conductive material. Option B: Have a la

I don't know if it's the best or proper way. We have a seperate jar that the paste that comes off the stencil goes into. All used paste( of the same manf.) goes in this jar and back into the refrigerator. The remainder of the new jar goes in the frid

Tented vias have solved problems for me in the past, but never created any. I have heard seemingly pointless discussions about whether or not the EE that designed the board designed it with filled vias in mind (a consideration of current carrying c

The german machines use the same basic procedure as the Compact Systems CS-400E but (to my knowledge) no cut and clinch. Can you give any information about manual visual inspection after stuffing boards with such machine. If stuffing boards without

We're in the market for a new depaneling router for high volume flex circuit builds. I have no experience with them. At this time, we do all our low volume stuff on a 3-axis mill. Any advice on what to consider and some recommendations of the best

I need some advise from those with experience on this component. We are facing soldering problem "pillow effect"(from cross section result)on this BGA. In the reflow profile point of view which area should we focused more? The soak time or the Total

Good Morning, I have an application that we are tooling up for that has several LGA (Land Grid Array) components. The Gerber files from the customer has a solder paste definition of 1:1 to the pad. As I look at this part, I cannot believe that this

Well, since you distinctly said *any* help.... as far as I know all of the GEM machine can use the original feeders, but there are as I understand it some newer smart models available for the X series machines. All I've actually used is a Topaz, th

Realize this thread is a bit old, but others may start inquiring soon... Just learned Biral USA in McLean, TX is no longer in buisness. Does anyone know of any other stateside distributers for the Biral T&D? Called 'Grainger' and they do not carry it
