Understanding PCB Manufacturing: Impedance Control

Posted by Michael Lesiak on Wed, Mar 05, 2014 @ 11:59 AM

Printed circuit boards with impedance requirements demand a high level of precision.

For standard circuit boards, a PCB manufacturer is given a set of patterns - copper patterns, hole patterns, ink patterns, which are combined into a single circuit board with all the pattern sizes and positions within certain tolerances. Failure to meet a certain size or position with the specified tolerance can be cause for the circuit board to be rejected. If a trace has been defined as an impedance control trace, it is not the trace size which is strictly defined, but rather the impedance. While a nominal trace size will be provided in the Gerber layer, it is understood the circuit board manufacturer can vary trace width, height, and dielectric thickness as long as the final impedance is within tolerance.

Understanding PCB Manufacturing: Hard Gold Plating

Posted by Paul Jackson on Wed, Feb 26, 2014 @ 08:51 AM

Plating Hard Gold onto printed circuit boards is typically done to provide contact points and PCB edge connectors.

Gold contact surfaces are often used on circuit boards with membrane switches which are a technology of choice for industrial, commercial and consumer products. When PCBs will be repeatedly installed and removed electroplated gold is used for edge-connector contacts or as they are more commonly known: Gold fingers. It is difficult to hear the term Gold finger without remembering the villain Auric Goldfinger from the James Bond film of 1964. However, the gold fingers (gold-plated contact pins) found on PCBs are quite unlike Auric’s stubby, fat digits. To begin with, the plating thickness of a PCB gold finger is typically a mere 300 micro-inch. At this thickness the hard gold is expected to survive 1,000 cycles before wear through.
