Jay: Can't harly beat the price, eh? Every year or so "Printed Circuit Design" Magazine (www.pcdmag.com ???) bench mark board software. Their benchmarks are on their site. How about using them to evaluated your software? And comparing that ratin

Yes,stencil supplier can give me some suggestion.but all need to be verified again and again.if there is such software can tell us everything about the stencil design? verify if before it be made.I do think it will save time to launch NPI and save ti

If you want some additional material on 0201 design and assembly the SMART Group Committee produced one of its Charity Reports with all the money raised going to the Red Cross USA September 11th Appeal. You can get it from the SMTA Main office, it fe

Greetings, Does anybody out there have any experience with 0306 capacitors (not 0603). I am trying to find a pad design for this component. I have searched the archives to no avail. The component is .06 long by .03 wide with .007" solder terminat

I have a SO-8 mosfet part from Vishay SI7846DP-T1. Am having a lot of solder ball that coming underneath the part. Am currently using a 5 mils with a window design for my stencil. Those anyone have experience or have any suggestion for an aperture th

We agree with Russ. The solderballs are probably the result of printing too much paste on the board. In designing your 5 thou thick stencil: * Aperatures for the pads should be identical to a IPC-7351 - SO8 [or worst case http://www.vishay.com/docs

1. Resistor is used to provide ground return for diodes. Diodes have a capacitance and with them floating a charge can build up. 2. They each perform different functions. The 100N is used for HF filtering. The 1uf is used for LF filtering and

Castellated is the easiest lead design. Anything longer than the out side dimension of the part should be OK. However, you will never get an inspection person to say it looks OK, yet the solder joint occurs on the bottom side of the part - like a B

You say that there is no green solder mask around the lands of the BGA only silk screen. If that is the case I would be concerned about the solderabilty of the component if the silk screen gets onto the pads. The application of solder mask is much mo

Yes. I'm at a loss as to how to best approach this. I think the giant blob of solder is just going to behave more like a lubricant than anything else. The thing is, I would like to at least try the manufacturer's recommendation once (and this bui
