Dear all: Does anyone know if there is any significance of the small numbers on SOT's. Do they have a special standards. For example I have one with just(A4), can this tell me any useful information? Thankyou. Hany

My company is looking for higher density for card layout. One suggestion has been locating active components packaged in SOT's and SOIC's on the B-side of the card. This in turn will require wave soldering of the above mentioned components. When I di
