I am using different equipements for SPI such as Koh Young and Cyber Optics machines. I am looking for implementing a general procedure (SWP) for setting LSL's and USL's on the products on which the customer does not specify any limits on the solder

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

1. The formula for cubic area (LxWxH) applies to get the expected volume target value. Caution- do not assume the pad surface square are is correct for the part. Do consider the footprint of the device beign placed and its solder requirements to cre

The NexLev connector is built in a stripline construction, providing a continuous ground plane for each signal contact. The connectors come as tenrow connectors with 100, 200, or 300 positions at possible stacking heights from 10 mm to 30 mm. Technic

Can you use the equipment manual as the basis for learning how to use the machine? Each model of printer has different alignment techniques. We don't have a clue of your model type. So, we'll approach the question from its most basic point. Registe

About the automated printing machines: They are all a little different, but the alignment part of the process is basically the same. I don't know if you have ever seen an automatic printer, so I'll do my best to explain it. The PCB rides into the

Hello PR, PumpPrint� technologies enable high throughput adhesive deposition using a screen printing platform. Careful selection of stencil material, and informed study of the design of apertures and other stencil features, enables a wide range of

hello, i have been using up-78 ultraprint for over a year now. at first we were getting lots of solder balls mainly on 0805's. this happened with all paste we used, too much solder under component leads. i have been using apertures reduced 10% homepl

| scott. | I appreciate your sincere answer. | would tell me the hint about printer if i's possible | To tune our smt process we have to know what is the major X's | for defect. To know major X's with DOE we need a good measurement equipment.
