Hi, Regarding to thermocouple placement, you should use a precision thin drill. Drill through the bottom of the board to the top as follows: One hole in the center of the part, preferably into one of the center balls, if available. One hole into the

You don't say which 265; presumbly since you say "bulb" it is either MK1 or GS with shuttered camera. Both those machines have potentiometers to control light levels. MK1 is on machine frame inside drop down (stencil load) door, near serial tag. GS

Put on your Chemical Thinking Caps..... We are ablating the mask of a PCB which was over a copper layer. This exposes copper. Outside of an electrical test (no can do) how could we use a fast non-destructive test in order to determine that copper (

When I was a little boy I saw a fly on top of another fly, I thought they were fighting, since fighting people make a mess, thinking we can not have fighting flys. So I whacked them over the head with the rolled up advertising section of a newspape

Quite sure it is one of the follow things. Squeegees are not tall enough (using after market blades); Are you using a stencil adapter? bottom surface of the stencil must be even with the top of the stencil shelves; printhead assy. is modified, faile

Thats a good one Dave. Sorry to say, but I have seen setups very similar for the mass repair of Playstations. Just add a heat gun over the top and you are ready for some rework! . And just LOOK at the controller! With E-Z turn knurled knob for setti

There is no easy way... but this is how I do it.. Origin the R axis, losen the idler bearings on the belt, remove the C clips at the top of the heads, lift up and remove the spindle assemblies being careful not to lose the 2 balls in the side of the

If it's using the laser alignment try changing the part type to "SOT" instead of chip, and then enter the dimensions for only the body of the component. The "Chip" setting will measure the part half way down the body, the "SOT" setting will measure

The smaller ball "missing" from the lower left is from solder migrating down into the adjacent via. The solder mask may have been damaged or missing prior to mounting the BGA device. The larger balls at the top right are due to uneven heating during

Hola I have this connector (atached image) for Wave Solder process, there is one pin with no solder on the top, for me it seems that the large trace connected to that pin is "stealing" the heat... I'm not WS expert... can it be corrected by profile?
