What you have run up against is the unfortunate consequence of the transition period from Sn-Pb to Pb-free. In the past 2-3 years there have been several studies highlighting the differences in reliability between mixed metal systems, Sn/Pb, and SAC

I have one form a year 2006. Uses the studds to keep track of revolutions. Four wires going to the motor.

You're correct it's a goofy question. Voltage is going to be circuit dependent, since the ball will be connected to the board. There's some ball dimensions in the fine SMTnet Archives ... they're about four times the diameter of your wires. If tha

The problem was that the wiring between the overtemperature capillary thermostats had burnt away. There are eight of these, four on the bottom half and four on the top half of the heat chamber. A rubber blanking grommet covers the adjustment shaft of

By no means clean room but pretty clean environment. We have ultrasonic air humidifiers maintaining our air at about 45 RH. I agree with you about airborne stuff attaching to electro-static. It's a mystery why it is isolated to four machine, thoug

We have four pick and place machines all exibiting a residue that seems to build up over time on wiring and electrical components. This residue appears as a white haze on wiring, caps and fuses (these are the components where it is most obvious). Y

If nobody else can help you and you are not afraid to add a bit of hardware, I would like to give it a try. If pistons are air activated there should be a solenoid for each piston. Locate the I/O signals, wire in a double through switch and apply 24

That's what we do [no more than three reworks or mods]. Your "four reworks permissable" was probably based on the 55110 five thermal cycles, counting wave soldering as the first cycle. How do you plan to keep track of each of those rework actions?

Jacky: There�re major four factors that affect the reliability of a solder connection. 1 Design of the connection including the shape and height of the lead and the type and amount of solder. 2 Dissolution of base metals into the solder connection.
