These patterns can be lifted and repositioned. All illustrations are 2 times scale unless otherwise specified. |
| EDGE CARD CONNECTOR FINGERS |
|
These universal fingers rub down separately, so 1X patterns work as DIRECT
ETCH resist. The extra length is for connecting to a plating bar. To shorten
a finger, 1) cut lightly with a knife (cat # 12161). 2) apply "Scotch"
or other brand cellophane tape to the cut section. 3) remove the tape along
with the surplus. JD-168 .060" x .500" fingers on .100" centers. .015" D pilot hole. JD-122B .050" x .500" fingers on .125" centers. .015" D pilot hole. JD-122 .080" x .500" fingers on .156" centers. .015" D pilot hole. |
| DOTDRAFT UNIVERAL PATTERNS |
| These Dry-Transfer patterns may be transferred Pad-by-Pad, allowing you to "build" any pattern that has .100" pin spacing and .300" between pin rows (i.e. any I.C. etc.) all without measuring. The 1X patterns may be used either in artwork or as direct etch resist on copper. |
