| We are installing a new reflow oven and I have been told that we do not need to vent the exhaust out through the roof since we have a false ceiling. All that is required is to vent above the false ceiling and that the air exchange is great enough t

| We are currently using a 65/35 solder for our wave process but are considering switching to a 63/37 for a substantial cost savings. No one here seems to know why we everused a 65/35 formulation in the first place. | I understand 63/37 to be pretty

| | Is anyone aware of some guidelines regarding through-hole in SMT pads? One of our designers wants to add through-hole leads in some SMT pads for an inductor. The size of the hole is 0.032 inches and takes-up approximately 25% of the pad area.
