Patent ID: 7637415

Claim:
A method for manufacturing a printed circuit board said method comprising: providing a board including a plurality of electrical traces, a first surface, and a second surface opposite the first surface; providing a plurality of surface mount components each comprising a plurality of electrical terminals; applying an adhesive on a portion of the first surface of the board and adhering a first surface mount component to the first surface; wave soldering the first surface of the board to mount the first surface mount component on the first surface, at least a portion of the electrical terminals of the first surface mount component encapsulated with a lead-free solder, and a first acute angle defined between the first surface of the board and a molten solder wave during said wave soldering, wherein the first acute angle is between about 4 degrees and about 12 degrees; applying an adhesive on a portion of the second surface of the board and adhering a second surface mount component to the second surface, after wave soldering the first surface of the board; and wave soldering the second side of the board to mount the second surface mount component on the second surface, at least a portion of the electrical terminals of the second surface mount component encapsulated with a lead-free solder, and a second acute angle defined between the second surface of the board and the molten solder wave during said wave soldering the second surface, wherein the second acute angle is between about 4 degrees and about 12 degrees.
