Splet3.4 Exposed Pad PCB Design The construction of the exposed pad enables enhanced thermal and electrical characteristics. To take full advantage of this feature, the pad must be physically connected to the PCB substrate with solder. The published data for thermal performance, θJA, is based on a four-layer PCB incorporating vias that act as SpletSimilarly, Gerber commands move a photoplotter head around a circuit board, exposing lines and changing apertures. The concept is the same but the grammar is different. For example, the PDF command “350 450 m” moves the pen to coordinate (350, 450). The Gerber equivalent is “X350Y450D02”. “.5 w” changes the PDF stroke weight ... http://stnms.in/admin/upload/documents/finalanswerkey/Final%20Answer%20key%20PCB-B.pdf shoes to wear with black party dress
