Maybe here's an opportunity to get a new oven. Electrovert, BTU and Vitronics offer closed-loop N2 control as an option. This, together with other improvements on oven design can reduce N2 consumption by as much as 40%. Not to mention reductions in e

Hi Grant, you have 2 good machines there. Thing to remember: Fuji machines need an external controller to run (Fuji cam or Flexa), you will have to buy that (extra cost). HSP have is own firmware include. HSP can do pick-up correction both in X and Y

I am currently looking at the volume of paste being deposited on a PWB 2.4mm thick with a 0.25mm tolerance. I am looking for information on PWB variation and a MPM AP25 series printer, and can the volume of paste be controlled on varing PWB thickness

Guy,s I do not have Red-e-set, but Grid-lok offers a fully automatic system that easily installs onto the printers and P&P. It can be set to your board instantly by pressing one button or triggered by the printer to set for each consecutive PCB. They

This may sound dopey, but it may be the answer to your question. ROSE testers from different suppliers produce different results. Look at MIL-STD 2000. Based on Table VII, you find the following upper control limits (micrograms NaCl / sq. in.): * M

People like flat surfaces for placing and reflowing certain components, like fine pitch devices. Some board suppliers can supply HASL that is flat and well controlled from an amount of material stand-point. Unlike OSP, HASL has a wonderful shelf-li

There multiple potental causes of BGA curling during reflow. One of them is moisture inclusion in the part, as Francois mentiones above in this thread. Another has to do with the construction of a BGA. So, from our perspective, more often the mois

We consider machine programs to be work instructions [WI]. [An instruction (or work instruction) is a prescribed series of activities, usually directed to a very specific area or process. Generally, an instruction may be done by one person.] Anyone

Hi CJ, if you need a rework station for any SMD's (fine pitch, BGA's, chips, SOT, ...), maybe you should also check ERSA that offers rework stations with computer controlled thermal profile (meaning you can apply a typical profile for each typical re

"I thought it was purely a mechanical up-down movement with the cam and hence the thickness hardly has any effect!" It is purely mechanical.On our high speed turret the machine knows the distance between the tip of the nozzle and the top surface of
