PCB manufacturing facilities routinely perform Electrical Testing with “Flying Probe” testers which are well suited to smaller production runs. For short runs, the flexibility of quick set-up ensures cost effective Flying Probe tests outperform the lead-time, cost and fixed designs of dedicated test beds. With Flying Probe tests, no fixtures need to be prepared, only data files. Flying Probe tests are able to reveal not only shorts and opens produced by the manufacturing process but have also been known to expose design errors. Flying probe tests utilize four to eight test heads, each equipped with a precision probe which moves to »»
Understanding PCB Manufacturing: Multilayer Assembly
One of the more interesting activities routinely associated with PCB manufacturing is the process of assembling multilayer circuit boards. At any given time 40% of our PCB manufacturing at Omni is producing multilayer circuit boards, so understanding the process is important. Layers of copper foil, prepreg and core material are sandwiched together under high temperature and pressure to produce multilayer assemblies. Pressure is needed to squeeze out air while heat is required to melt and cure the thermosetting “prepreg” adhesive which holds the multilayer PCB together. Manufacturing process for multilayer PCBs Manufacturing multilayer circuit boards is a straightforward process but does require a »»
My Rants -- Current List
These are my rants, sadly, a growing list. I’m unhappy that: Opening day of Major League Baseball [MLB] is no longer always played in Cincinnati. Baseball games take too long to play. Pitchers prance around on the mount scratching and adjusting themselves. Batters prance around home plate scratching and adjusting themselves. Here's my solution: ** Pitcher steps-off the pitching rubber: Umpire calls a ball. ** Batter leaves the batter’s box: Umpire calls a strike. 2002 All-Star Game, held in Milwaukee, ended when both teams ran out of players available to pitch. At that point, Commissioner Bud Selig declared that the game complete after 11 innings »»

Printed Circuit Boards Supporting Our Future
Over the course of a year, our Omni website receives over 900 visits from students and instructors from more than 45 academic institutions located around the world. It all started in the early days of the Internet when Omni was one of the very first PCB manufacturers to create an accessible web site. Being one of the early adopters provided us an opportunity to support and collaborate with some of the more prestigious universities on the planet and the tradition carries on today. [ We took recent site visits to Omni and plugged them into Wordle. ] Throughout the year, we provide technical »»
