Silly question, but, are TR blades 'exactly' the same size as MPM's and seat themselves in the holders just like MPM's? Also, different types of steel are harder (less flexable) than others. Are TR's the same? If harder (due to steel strength or coat

We expect to see a copper shadow along the edge of pads when soldering boards with organic solderability protection [OSP]. IPC-A-610 has defined this as acceptable for years. During early reflow stages, the flux in paste dissolves the OSP where ther
