I feared so. The only thing to be done is to tell the PCB manufacturer to increase the Thermal cure so dont set the oven to 150C but to 170C and actually measure the middle board and once it hits 155C then give it an hour cure from then. Also insist

| It seems to be that we have to much NaCl left on our assambled PCB's. | The flux we use is from cobar. They say it can not be from the flux... So what can be the reason, what kind of problem may occer when there is to much NaCl. | George: When so
