. If the flux is not qualified, that is a defective condition for both Class 2 and class 3 products. Hence the fluxes used for soldering cables and wires should be a flux, which can remain on the product and not need to be removed

. The alloys of SAC 305 and Sn100C will work together so mixing of those two should not be a problem. The concern, however; is the flux and can it be removed after the replacement of the component

. Trace and Via are now separated should one be excluded.If the Top Pad of a Pad Stack is Complex, while the regular Pad Stack name is not, the two values will be concatenated together, spaces will be removed, and COMPLEX will be shortened to CMPX

the components when they are melted. If the removed component is still needed, then try not to face the center of the component when blowing, and the time should be as short as possible

. Additionally, the floor should be conductive or the foot straps will not work. The intent of the grounding straps, be it foot straps or wrist straps is to reduce the static electricity potential in the human body, so when working with ESD sensitive products, they will not be destroyed

? Usually, no. Solder paste should be used as needed. Material should be left at an acceptable room temperature once removed from refrigeration

. When the tinning on the tip is gone, or the tip cannot be tinned, that oxidized surface is a poor transmitter of heat and energy which is required to melt the solder to make the solder joint
