SMTRESEARCH.com has an excellent machine POD. I have yet to get a demo on it but the litature looks great that they sent me. We are using fujis DT651 which is good a machine. It isn't as user friendly to decipher the results for machine faults as th

I'm currently working in a SMT factory in China. I'd like to know what preparation that I would need to change from leaded to lead free soldering. 1.Starting with the PCB production, things that I need to concern about are solder mask, Cu protection

Hi: I am wondering what others are doing that use a Static Ionic contaminate test (e.g. Ionograph/Alphametals) in relation to time. Our Ionograph has the option of setting a test time, or setting it to auto-terminate when there is no change in resis

It depends. We've known cases where 10 mohm-cm was insufficient and others where 0.1 mohm-cm was more than sufficient. No standard exists. Our final rinse is fed from a recycling unit that produces DI water. We use 0.5 mohm-cm resistivity as the lo

Not sure of what a bench top DI setup would look like. I use 3.5 Cubic foot tanks but have a special application that uses a 1 cubic foot tanks....even then its not a bench top setup. What is clean. No one can tell you. YOu can use IPC TM650 or t

In obtaining almost zero defect in solder wave. I would like to suggest the following: First,We must consider changing machine if it is more than 5 years old. second, use the right tools for the right job. Most of the traditional engineers will us

Hi All We have two boards that we produce which are chip on glue. For this we use KME BD12's which use air to dispense the glue dot on to the board. This is not ideal as the glue dot size differs as we go down the tube causing us quality problems.

We currently use a KIC 2000 system to profile on our oven and create our recipes. I had a customer in today reviewing our profiles, and he had concerns that we were exceeding 4 deg. c/sec. on our profiles. The process window parameters that we use

You can make one out of a stainless steel tank pretty easy. Cost maybe $1000.00. You will need some hot plate type heaters and some copper tubing with a water flow source to keep the vapor down in the tank. We used two fluid types so one blanketed t

Hi Everyone. Are many of you using Bravo 8105 reflow ovens with chiller units? What have your experience been like with them. Are they reliable? If you had the choice would you get another? Is having them an advantage with lead free production?
