Any one encountered the problem such as poor conductivity when the silkscreen mis-registrated on the solder pads ? Thanks; Linh

We have had poor solderability from silk screen being on pads, but have never measured the conductivity.

One of the DFM suggestions I've seen is to remove the solder mask web, i.e. the mask between pads on 20-mil QFP devices. The rational is that if the mask is thicker than the pad the mask can prevent the stencil from making intimate contact with the

Hello! Does any one know of a disadvantage of using the Phillips recommended wave solder SOIC footprint where the last pad on each side of the SOIC is enlarged, instead of placing an extra pair of pads behind the SOIC. Both footprint patterns seem e

This is not strictly a surface mount query but any input welcome I am thinking of using surface mount solder thief pads for a through hole connector. The connector is two rows of 0.1" pitch pins and on waving there is often a bridge on the last two p
