Interesting you should ask this what problems are you seeing. Non wetting and blow holes and shallow fillets at all??? Cheers Greg

Blows holes are usually caused by improper amount of flux applied to the boards prior to WAVE process and, in some circumstances, can be related to the preheater settings.

Hello Hoss Voidin/blow holes can also be exacerbated by residual flux. Have you experimented with dwell times and separation speed parameters with your selective ? What related parameters are you currently running processing under ? regards Jim

I'm sorry. These are SMT caps such as a C0805C271J1GAC. Small 0805 caps. I know they gennerally give you solder balls that sit on the side of those parts but they wash off.

John: Secure the capacitors that you removed from the machine ... * Removed capacitors have a problem * New replacement capacitors don't have a problem Find help to determine the difference between the two reels of parts

| Recently, there has been an upsurge in the Pin Hole/Blow Hole problem in our wave soldering process. We are baking the PCBs for 2 Hrs. at 125 degree C. The Wave Soldering profile seems to be O.K. Still the problem is persistent. Can somebody hel

Let's talk pin holes and blow holes. I've been here since the transistion of leaded to lead-free process started for our company and we purchased a wave machine just to keep up with our lead-free orders. we put out 500-1000 boards a day both leaded a

I am looking for someone using Wanesco Soldering Station with hole blow-off option installed.I am trying to set it up using hot air. It is provided with special tips with rubber lining to seal off the slected area. But it leaves few holes always bloc

We build a mixed tech [eg, QFP, SMT fly shit, DIP] board where we can't clinch the DIP. So we set the clinch and cut on the DIP to just barely clinch, leaving the leads very perpendicular to the board. I wonder if you could do something similar wit
