Did you try 0.12 or 0.1mm nano coated stencil @ 10 mil aperture? A soak time type profile with long reflow time could help.

For space contracts we have to mount chip capacitors/ resistors etc 0.1 to 0.4 mm from the pad height. This is to compenstae for the CTE differential in the substrate/component and also to ensure cleanliness. Does anyone have any new ideas on how t

ENIAC, 0.040" equates to 1mm, not 0.1mm. 0.040" is the IPC minimum recommended fiducial size and when we started putting fiducials on our boards I assumed that all equipment manufacturers should be able to automatically spot that size. Since then I'v

Hi We have just specified the following thicknesses for the Nickel and Gold on an ENIG finish board. The baord is to be manufactured using a lead - free process. My question: Is the thickness we've specificed likely to gie us any issues during manuf

It is not all of the product. It is per separable homogeneous material. A 0402 coil could be broken into at least a half dozen pieces and each piece is separate. Look at the size of a single 0402 joint. How much lead would 0.1% be? Not much. A custom

From my understanding: Sigma is the same as one standard deviation. So 3 sigma is the same as 3 standard deviations. It all boils down to how repeatable your machine is. Another way to look at it is the probability (or confidence) that the machin

I get the MCV thing. I dont see it spelled out anywhere when it says each component is to be treated singularly. To me �...a maximum concentration value of 0,1 % by weight in homogeneous materials for lead, mercury, hexavalent chromium, polybrominate
