Systems And Methods For Drilling Holes In Printed Circuit Boards
Systems And Methods For Drilling Holes In Printed Circuit Boards
US Patent:
2013005, Mar 7, 2013
Filed:
Oct 30, 2012
Appl. No.:
13/664344
Inventors:
JAMES JOSEPH MILLER - BREA CA, US
PAUL RONALD ST. JOHN - CORONA CA, US
PAUL RONALD ST. JOHN - CORONA CA, US
Assignee:
TRI-STAR LAMINATES, INC. - LAKE FOREST CA
International Classification:
B32B 7/02, B32B 27/38, C08G 59/06, C09J 7/02
US Classification:
428215, 428220, 428337, 523400
Abstract:
An entry sheet comprising polymer material for drilling printed circuit boards is provided. The entry sheet is suitable for use with a broad range of diameters, including commonly available drill diameters. The entry sheet comprises an adhesive epoxy configured to, among others, resist drill deflection, resist mechanical damage, and reduce to dust such that the entry sheet may increase drilling accuracy, protect printed circuit board from damage, minimize entry burrs, and may addresses other issues such as fliers, bird nesting, and the like.

International Classification:
B23B 3500, B23B 4114
US Classification:
408 1R
Abstract:
A method and materials for drilling through-holes in printed circuit boards with a drilling tool is disclosed. The method involves the use of a lubricating entry material placed on the top surface of a stack of printed circuit boards and a lubricating backup board placed beneath the bottom surface of the stack of printed circuit boards. The lubricating entry material has a core with skins attached on both sides by a lubricant/adhesive. Similarly, the backup board has a core with skins attached on both sides by a lubricant/adhesive. The skins are hard enough to support the top and bottom surfaces of the printed circuit boards and thereby reduce burring at the entry point and exit point of the through-hole. The lubricant/adhesive coats the drilling tool during the drilling operation to reduce friction and thereby reduce the temperature of the drilling tool.
