I want to know the answer to the following question:
In through-hole construction, what are the leads on the front attached to on the back?
All the background I'm provided with is that "Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on the back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends.". Is that enough to answer the question?
