Abstract:
A method for manufacturing a modular board comprising the steps of:forming a through-hole in a bare board; providing a back electrode surrounding the through-hole on the bottom surface of the bare board; providing an edge electrode, connected to the back electrode, partially or entirely on the inner wall of the through-hole; cutting the bare board along the through-hole to form a split board having the back electrode and the edge electrode, and a remaining bare board; providing an adhesive compound containing an oxide removal substance on the periphery of the through-hole; attaching solid solder to the adhesive compound; heating the split board and the remaining bare board to melt the solid solder; and cooling and solidifying the molten solder on the edge electrode and the back electrode for bonding.
