Thanks Rob. I'm not so sure in a mass production environment that using the mount spray and kapton tapes are going to be efficient. For solder paste dispensing, any idea what is the smallest solder dot size the machine can dispense?

Hi Rob, So do you have to constantly remove the old adhesive and spray on new ones? Is that an automated process? Also for the kapton tape removal and application, is that automated as well?

| We are facing a problem of high contamination on boards after wave soldering. We want the contamination to be under 24 ugm/inch square. We are using a no clean flux with the spray fluxer unit of wave soldering. The contamination is higher on the e

The Contamination has proven to be pretty random, lots of stainless steel though in fact two cases in the past two days. As far as I know all machinery is cleaned regularly as well, even the stencil washer itself. The boards we make are 90% (at l

Chrys: I have checked all the basic elements of Wave solder joint formation: fluxing, preheating, and lastly soldering. For checking the fluxer, i used a product from ECD that's very similar to what you desribed called the flux-o-meter. It did a

Ken: Sprays like you suggest are hydroscopic soaps that should be avoided. If that was the choice, we'd rather go with Russ' ioniczer.

Does anyone know where to get Biral T&D and Threebond Spray oil other than their Web sites?

Hello Mark, I wish it were that simple so I could direct you to a particular manufacturer and stencil cleaner model. Unfortunately, there are several issues complicating the process of cleaning all these applications in one machine. First and fore
