Hi I recommend you to check the exhaust sensor, the ERSA EWS500F is sensing the exhaust before it activates the fluxer. If the exhaust is not working then machine does not start to avoid the sprayed flux emit to the work environment. There is a sens

I have sucessfully networked our GSM1 into WinXp network using NetBIOS. I was able to access shared folder on the XP server from GSM and we are using that connection for backups and new product imports. Our machine runs on OS/2 V2.11, but I think tha

What is your squeegee pressure and size. Also does the pad sit on a ground plane, as it looks like it is partially reflowed so surface has gone but not coallesced properly which would indicate it is more a problem with reflow above 217-219C OR obviou

We have recently begun using X5R dielectric capacitors. Although they have a better temperature coefficient over Y5V, they age much faster (5-7% logarithmically per decade). I assume the reason for using the X5R was the availability of the capacita

We have had issues for the last 4-5 years with converting our stock from leaded to ROHS components. We are a CM and have customers who want all ROHS and some that are still leaded. The problems we run into are when we intrduce a new ROHS component wh

Dave, We have both situations where the grounded electrical equipment on the mat has insulative pads or does not have insulative pads. The workstations we have this problem with are test stations where electrical equipment is used on the test bench

Nuez, I don't really see how it's a problem. If your not using a wrist strap, there's no grounding issue. It will work fine as is, equipment insulated or not. The "conductive" mats have many mega-ohms of resistance as it is. Simply "bypassing" t

Advertisements are not always 100% accurate on technical issues. You don't want instand static discharge. A wrist strap with no resistor could cause that. Therefore put in a current limiting resistor to make the charge dissipate slowly. Does anyone

Hello everyone, I have a question regarding rework. How do you guys rework QFPs (lead free)? The only method that we are currently doing is using a heat gun. We are heating up the bottom of the PCB (approx. 2") away from the bottom of the
