We have an internal debate whether to calibrate equipment using K-type thermocouple made out of : 1) fibreglass braided, with a 482 deg-C peak-measurement properties? 2) teflon FEP(fluorinated Ethylene Proplene), with 204 deg-C peak-measurement p

Second the motion for the Stevens Products covers. They call them Gold Fingers Gloves and they are a pull-truded fibreglass product that comes in sticks. You hacksaw them to the length needed. We have many that have been through the wave thousands o

I had something similar a while back it looked like fibreglass insulation in my case (was using no clean flux not water based), i took some and melted it with a soldering iron and it reacted like flux. and i tried disolving it with acetone.

Hi Is there an alternative material to fibreglass that can be used for PCBS ? for a specific application I am looking for something that will absorb little or no moisture. Regards

Hi Dave, Bbbaaa....*note the sheep eyes*....bbaaa.... ok, that was a great wakep up rap! I'll relay that strongly worded paragraph to the calibration in-charge, see what he has to say for himself? thing is, such situations reflects on us as a whole

I built myself a reflow oven using an off the shelf 29l fan forced oven with digital controls. I then fully insulated the cavity around it with kiln fibreglass, and added a metal infill at the back as the back of the oven was just a metal sheet. Anyw

As stated in the title I would like to know the thermo-elastic material properties, most preferably the E-modulus and CTE in x- and y-direction, for Epoxy/E-glass laminates and/or prepregs for various fibreglass cloth styles. Datasheets only give ro

To get real conductivity in your traces you will need to remelt your copper or silver tracks. This means 850oC. The other method is plating at low temps, or etching. Epoxies like all carbon based compounds vaporize at 400oC. Next problem epoxy fibre

Oh great!!! You do calibrations, what once a year? And NOW yer in a BIG �time is critical� rush. �Speed in reply is appreciated.� And why couldn�t you have asked this question 6 months ago? Just what have you been doing since the last calibratio

| | | | We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design)
