iT HAS BENN OUR PRACTICE IN THE PAST TO BAKE OUT PWAS BEFORE SOLDERING AT
EITHER 185 DEGREES f 0R 185 DEGREES F DEPENDING
ON WHETHER THE ASSEMBLIES OR BOARDS HAD BEEN PREVIOUSLY BAKED OR NOT. tODAY
WE ARE DOING SMT AND SELEWCTIVE SOLDERING.
MY QUESTION IS," WHAT DO OTHER PEOPLE DO ABOUT BAKING BARE BOARDS,
ASSEMBLIES ON INITIAL SOLDERING AND BEFORE REPAIR?
aLSO, WHY DO YOU BAKE OR NOT BAKE?
