Can't agree more than moving over to Homebase apertures, But ensure that the cut back angle is correct,to acute of and angle will leave you with an inadequate contact area fot the terminations on the chip components and you will start seeing insuffic

I second Wolfgang. Welcome, It's good to hear from someone who wants to design something we can build. Another useful resource is the land pattern book from SMT Plus www.smtplus.com 831/438-6116 Also useful are the component mechanicals available (fr

I was running the conveyor at 3.75 when we started the discussion with Electrovert. Unfortunately, foam fluxing is a fact of life for us. Our products have open contact relays that can become contaminated by spray fluxing. Titration is our only me
