Why can monitor manufacturers learn to solder properly?
I can think of several potential reasons – all solvable but at higher manufacturing cost. • Mass of large component leads (like shields) does not get adequately heated during manufacture leading to latent cold solder joints. While they may look ok, the solder never actually ‘wetted’ the heavy pins and therefore did not form a good mechanical or electrical bond. • Thermal cycles and differential thermal coefficients of circuit boards, traces, and solder. While it is not easy to do anything about the material properties, using plated through-holes or a similar mechanical via would greatly increase the surface area of the joint and prevent the formation of cracks. • Vibration. This is also directly related to the single sided circuit boards without plated through-holes to strengthen the joints. • Lack of adquate mechanical support (single sided circuit boards without plated through-holes (vias). I believe that the single most significantimprovement would come about by using plated trhough
