Omni PCB boards on the cover of Time magazine

So how would you respond to appearing on the cover of Time magazine? PHOTOGRAPH BY GREGG SEGAL FOR TIME We recently received rock star status in our local network of manufacturers by having our PCB boards featured on the cover of the February 17, 2014 issue of Time magazine. Okay, it’s not the cover of Rolling Stone and the image is kind of small and fuzzy but still we were pleased. Now to be honest, the issue featured the work of one of our more prestigious customers: D-Wave Systems, Inc. and our circuit boards were only one part of the assembly shown »»

Understanding PCB Manufacturing: Impedance Control

Printed circuit boards with impedance requirements demand a high level of precision. Image courtesy of Zmetrix 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 »»

Understanding PCB Manufacturing: Hard Gold Plating

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 »»

Developments in Aluminum Trace Circuit Boards

As you might expect, no two applications for aluminum trace circuit boards are the same and most often they are not even similar. While some customers are investigating frontiers in MEMS (Microelectromechanical systems), others are delving into the inherent superconductive properties at milliKelvin temperatures, while still others are exploiting the radiation response characteristics of aluminum. For the R&D personnel at Omni Circuit Boards, the requests have presented some interesting challenges. Can you provide selective copper pads to enable even stronger solder joints for ZIF connectors? Yes, we can. Through a series of tests, we were able to reliably produce aluminum trace printed circuit »»
