Evaluation of Drilled Hole Quality as a Function of Speed and Feed in Multilayer Boards
R.E. WeissStudies of the drilling process have shown that a direct correlation exists between the quality of a drilled hole and the energy expended by the drilling system in forming the…
Measuring the Thickness of Coatings on Printed Wiring Boards
T.D.T. LatterThe Beta Backscatter Coating Thickness Gauge has been a very well used “tool” in printed wiring production for many years. The increased requirement to more closely control the…
Circuit World Visits TDS Circuits
Cooling towers, slag heaps and rows of back‐to‐back houses, or the decaying buildings that George Orwell described as “festering in planless chaos”, are only one aspect of the…
Designing Plating Equipment for PCB Production at ELECTROLOID
Members of the printed circuit board industry have sometimes complained that plating plant manufacturers rarely design anything specifically for PCB production. Apparently new…

I/C Packaging and Interconnection Developments
M.G. SageThis paper describes the major new I/C packaging technologies now coming into use, i.e., chip carriers and tape automated bonding. It deals with the reasons for their development…
Some Practical Aspects of Flexible Circuit Design
T.P. HoganFlexible circuits are true components in their own rights—not solely replacements for discrete wiring—and must be designed as an efficient component for production. This paper…
The Use of the Laser for the Inspection of Printed Circuit Boards and Laminates
