APPARATUS AND METHOD FOR MANUFACTURING PRINTED PLATE BOARD |
摘要 |
<p>PURPOSE: A device and method for manufacturing a printed board are provided to prevent cracks due to thermal stress by fixing a gap between a semiconductor chip and the printed board with under fill. CONSTITUTION: A solder bump(39) is printed on the surface of a printed board(33) using a solder ball printer. The solder bump is fixed on the surface by a reflow process. The printed board is mounted on a table. A protrusion(40) is formed on the peripheral part of a film(30). The protrusion prevents a semiconductor chip(41) from moving when the printed board with the semiconductor chip is moved.</p> |
