I feel as though I�ve just walked in to a bar, where everyone I was supposed to meet has been drinking for 3 hours. First, the volume of water displacement thing doesn�t make sense, as others have commented. Second, I believe Dave Robbie wants meas

Some use small cleaners but I have always used the stencil washer. Most stencil washers come with a basket of some kind of board holder (or via holder - depending on how technical you want to get). Buying a stencil cleaner is hard to justify just f

Hi robinj As you have mentioned, if the color is yellow usually it is caused by moisture left on the boards from poor drying after immersion silver. However, our boards were received from the supplier and the changes happened in our side. So, what di

Thanks for your reply. I 've tried to clarify and answer your questions. The water soluble paste used is WS3060, type 4. The boards are sent through a inline di cleaner after reflow. There is a hot Di waterwash, rinse and then hot air to dry the wa

We are having problems removing the flux residue from our boards in our batch cleaner. We use Indium SMQ92J which I hear is notoriously difficult to remove. Can anyone suggest a similar paste (price/performance) that has better results with cleaning

Yes it happens with any inline cleaner with small or light boards the pressure can cause them to flip. If they lodge in the links they can also cause damage to the conveyor. For small boards, flexibles etc you do need a mesh fixture of some sort or l
