The connectors are well within thier specification,and are also checked for misaligned and damaged pins , as regards the cross-section results, all holes are correctly aligned and are well spaced within their tolerance of +/-0.005 (a couple of isolat

Hello, Standard way to calculate stencil design can be done as follows: A normal ratio of aperture width/stencil thickness = 1.5 for pitches below 650u A normal ratio of stencil aperture width against pad width = 0.8-0.9 (or stencil aperture 10%-20

I just saw a pre-release demo for the 8.0 AML functionality, which should do the job. Our assessments and concerns with the different ERP's are similar to yours, for example in not wanting to go with antiquated implementations. My question is, if yo

Alberto: There's no rules, but it works sorta like this: RESISTORS Usually marked in ohms using a standard code: First two numbers is the value Third number is the multiplier 102 = 1.0 x 10� ohm = 1000 ohm = 1 kW CAPACITOR Usually not marked. When

You could reduce the paste by about 70%. Solder balling and tombstoning will be the issues to fight. The drivers to these don't change with the component size. Use the fine SMTnet Archives for background. Aperture Size and Thickness of Solder Pas

If this code is on a ceramic cap then it is a 0.1uf cap. We have a conversion charts that list most all codes. Useing the last 2 digets only determine the value. The capatol letters A thru Z are given specfic numerical value. Example A0 is 1.0pf, A1

| | Where can I find a spec to put on my fab drawing, to call out the cleanliness of the board, before I recieve it. These boards will require a tight spec after they are assembled, so I want to know that they are clean when I get them. Any suggestio

Peterson: Ionic flux residues when combined with moisture and a voltage differential can plate conductive �fingers� on the surface of a PCB, but that doesn�t sound like what�s going on here. Your NC flux should not be particularly conductive. For
