Well, at least Russ actually got to speak with someone! I called and left a voicemail for Mr. Larry Kay, the President of PKay Metal. I do not believe I have ever experienced this much difficulty actually getting a company to sell a product. Anywa

We do the same as SR Tech but add in a check of the thermocouples the oven uses to monitor it's own temp. Annually I attach a thermocouple from a calibrated thermometer to the thermocouple in the oven. I compare the readings. We specify a plus min

That's why I parallel ported the T/C's. Now I can use a calibrated hand help thermocouple and plug into the T/Cs on the oven. If they're within about 3 degrees of each other, then they're considered within our specification. Paper work on the hand

Hi Grant, Most inspectors want your oven temps close to what you normally run your product. I've had to show both glue and past profiles on every oven before. Then they want to see if you are matching the profile specified by the manufacturer. I

Thanks everyone, I have found your postings very helpful for reflow ovens and intend to review my reflow calibration and validation, but in this particular instance I should have been more specific. We use the non conveyorized type of oven (Ten

Certain paste mfg specify 6 hours paste thawing time to normalize the temperature. I am using solder paste softerner to spin the paste taken out from fridge for 9 minutes and measure the paste temperature in jar.It is around 26'c(same as the ambient

I'd check around for a wire solder that doesn't leave as much residue behind or a "clearer" residue behind. Or tell your customer you can save them a few bucks by just soldering a few points on the lid (since it's a air tight seal).

Hello, I know for sure that using lead-free technology in conventional tin-lead machines makes a lot of problems. But I wonder if we can use conventional tin-lead alloy and components with a lead-free machine! Is it possible? Does this imply any s

Yes, it's fine - as Pete says you have to replace certain parts & either get the pot recoated or a new one. We ran a "Lead free" 6622C from Vitronics Soltec on Tin Lead, then it was cleaned up, recoated and loaded with a no-lead alloy with no proble

I need to change Drill holes sizes in a PCB from 0.6mm to 0.55mm. Do it need to change anything else other than the Drill hole size in the INfo section of the Gerber file, for example do i also need to change the artwork of the other layers if the dr
