I have seen a method used where the pins on the connector are of the same materials as the thermocouple and the connector is connected via single strand wires of the same material to the PCB however the wires were spot welded to bare copper pads to r

We're running an older TP9-U, and clocking in somewhere around 3000 cph, realistically. Placements, however, are very accurate. Works fine down to 0402's, high-pin count QFPs, etc. My -U doesn't do great on optical centering...it works, but it's a

Hello, Is anyone using an SMT pick&place machine to insert single contacts into PC boards? I have some boards that have 32 female contacts for 1mm pins, and 16 contacts for 0.5mm pins. I have been using Mill-Max for these contacts, getting the sma

We have a problem with soldering of a 96 pin header connector(9001-11961c00l1a from kingmate) we use 3 different wave soldering but in all of the machines we have many short circuit between the pins . the wave soldering machines that we use is fr

Desoldering often applies a LOT more heat and thermal stress to the part, and maybe mechanical forces while everything is hot, to get the part free of the board. So, a lot of damage might be done there, making post-mortem harder. Without the leads,

Paste stored tip down, so separation in the tube is not suspect. Remember that the defect was produced on a screen printer running with a Rheopump. A few more details are that the strip of the board containing the uncoalesced solder is consistent w

I would rethink your schematic. If you are using D1 for power indication, put D1 in series with a 1KO resistor to ground. D1 will 1.5-2.2V which will your supplies voltage to your 555 timer. What are you driving on the ouput at pin 3? If you ar

I don't have CircuitCam, I'm using Unicam with Mydata. In Unicam I have a Theta Offset setting for each package witch determines the default rotational angle with respect to the pin 1 setting within the package data. With Mydata, the package inform

Hi, I bought a Philips CSM84 machine 2 weeks ago. I have no experience on SMT machine so I try to learn everything from the manual. There is an error message when I program a simple program and try to get it executed. "PCB FIXING ERR. LOCATE PIN NO

Hi Tom, You're right. I do find the second locating pin hardware. Now I got them both up/down when F3 is pressed. Thanks. I don't see any pin on the hardware and no edge clamp hardware either :-( , do you know any way that I can bypass these hardware
