The beamworks new software on teh 100 is great but went to outstanding when the 60 watt leser was installed and the performance went up 60% in speed. The new software requires the temp of the solder for melting and the ammount to be despenced and the

We are currently building a board that has large pads that are for multiple SMT parts. There is no solder mask on the PCB in these areas to seperate the terminations of the parts. The parts tend to pull together in reflow. Can anyone recommend a g

Morning all. So today I have been tasked with conformally coating a few of our first run PCBs for a new product line. The problem is that they have already had all the larger caps potted with RTV. Are there any problems with spraying the CC over the

Well that doesnt sound very promising. What im going to do is make sure these two boards I just coated (with the RTV already cured) will be used in house only. In the future we will do any conformal coating operations before potting with whatever mat

I have a Siemens SP-120 and an HS-180 available. Can the SP-120 be used without a line computer installed? Possibly using the HS-180 computer? We are looking to use the machine for short production runs and prototying. Thanks in advance for an

How many times can I reflow SMT components such as SMT Ceramic Chip Caps (0603 and 0805), Res Caps, TSSOP's, SOIC's Tant Caps etc? Will I have a problem exposing them 4 to 6 times of reflow? Will I damage them? What will go wrong with that process?

I have found that Sn62 solder gives better strength and leach resistance when soldering to gold surfaces. The gold needs to be at least 5 to 10 micro inches thick to prevent nickel oxidation but if over 25 micro inches will cause brittleness. I hav

It was a resonant frequency that brought down the Narrows bridge. Memorex can shatter a wine glass with resonance. Ultrasonic washers use frequency to do what they do. If anything on the pcb has a length width or mass that resonates at the washers fr

I always have a difficult time with seeing people using two different manufacturers products. Here your printing with Senju and hand soldering with Kester. So if theres a problem you have to look at two different products, contact two different compa

So I guess we could repair with the 63/37 until 7/06 then. We should be able to facilitate and figure out easy/ cost effective repair by then I hope. Senior Tech - I don't know who I am talking about when I say "we", lets ask Dave again, maybe he k
