Making The Connection
This article describes how rapid technological
change in the circuit board fabrication industry has affected the
through-hole drilling process. The choice of drill bit, entry material
and backup material directly affects the through-hole quality of a
circuit board. By selecting the optimal combination for your application,
your circuit board fabricator can meet the technology, quality and
cost requirements of your product. |
How Clean Is Clean
This article explores three prevalent
test methods for determining the cleanliness of bare circuit boards—visual
examination, solvent extraction and surface insulation resistance
(SIR) measurement. The advantages and drawbacks of each method are
discussed.

Using AOI To Improve Quality and Yield
The use of Automated Optical Inspection
(AOI) systems is a very efficient method for supplementing process
control and improving quality levels. This article provides guidelines
for selecting the AOI system best suited to identify and remedy problems
with your company’s manufacturing process. It also describes
the advantages of laser-based systems for performing automated optical
inspection of component placement on circuit boards. |
