What type of flux is in your solder paste? Active or No-Clean? With lead free solder you really should be using an active flux. The lead free oxidizes during reflow if you are not using a Nitrogen or Vapor Phase reflow. So a more robust and activ

I would cut a piece of cardboard to the same dimensions as your circuit card. Run that through the fluxer of your machine and pull it out before the pre-heater. Take a look at the cardboard and verify that flux has been sprayed on it. That board look

Wondering how many out there have upgraded their AOI systems to 3D technology? For those that have here are some questions I have: 1.) What system were you using previously? 2.) What systems did you evaluate in your process of selecting a new syst

When i considered using one I bought a cheaper brand named aoyue which cost less then $140 U.S. just to see if it would work for what we were trying. It did work but our engineering dept wound up scrapping it and doing a redesign. I was going to get

kalsi, it looks like you are more comfortable with Mirae. From reading your post, you guys set the Mirae faster and better than the Advatis, so I think the answer is clear. Many discussions here mentioned that the machines are as good as your unders

When you go repairing resources like one time copies of an installed OS for a machine like yours , you have to treat it like your life depended on it. So get a copy of the harddisk before you attempt to repair it no matter which methodology you use.

I'm aware of no electrical test for detecting voids and air bubbles. If someone was x-raying my boards and saw voids and air bubbles and they weren't happy about it, first thing I'd do is convince them that the boards a within standard. You know some

I've used VJ Electronics Summit series of rework machine. I liked the programing interface. You can used canned scripts for basic removal/replacement processes or you edit/write your own if you want a customized work flow. The machines are very ope

40 parts per board multiplied by half a million per year is 20 million placements per year. That’s serious production. The machine is rated at 7500 placements per hour, so running 24/7 that’s 111 days per year. The rated placement rates on pick and
