most pick and place machines will run for a very long time provided the operators keep them clean and well lubricated (10 years +). Often we end up replacing equipment not due to inoperability as much as due to capability. as packages and use chang

I have waved gold (ENIG) boards. That's a pretty hot pot at 260C, wow. I have used 245C with good results. All other parameters look OK a glance. Well, PCB temp looks a little hot too at 130C before pot. 90-100C is typical for most No-Clean flux. At

Snaggie Oxidized nickel is very tough to solder. Using the typical fluxes that are in everyone's fireproof storage cabinet [that they've been sampled by very nice saletypes] is like bringing a knife to a gun fight. Recognize that the flux you want

I'm assuming the fracture in tension; the fracture doesn't show even at X50. The broken edges are that clean. I would expect spalling at the fracture edges if it were a compression or torsional fracture. This makes me belive the board expands and pul

Putting aside that you want to: * Get this mess cleaned-up as soon as possible * Stop spending money on this issue * Get your volumes back to plan ... and all that other production meeting stuff We'd be very nervous about shipping the X7R dielectric

Hi, So that's really important to have a specific flux for lead free? We are looking at changing to SN100C after reading this thread and other stuff we have found, so can anyone recommend the best no clean flux for that metal? Do you need differen

There is no set formula. You need to customize this number around your operation. Depending on how you account for: Capital Equipment Costs Utilities Building Costs Overhead services Consumables ( Flux, Paste, Glue, ...... ) Once you get the costs

Yes, I agree Pete. The industry is zeroing in on: Hi-Rel / Industrial = Tin-copper-silver Consumer / low-end industrial = tin-copper I worked for a company, directly developing lead free processes for a major consumer electronics manufacturer. W

i have a problem similar to Daxman where cp6 usually having problem when it run at high speed, the head seems to have problem returning back to its origin at st12 and stop at st15 and st19 for nozzle change error, when rotating the head by hand, some

Dax, You need to clean out those clutches. Even if they seem OK they can still get varnished up and cause minute alignment problems. I think I mentioned before that you can get in there with a Q-tip, but the true way to get them perfect is to take t
