Blue Eagle Pins Concentric Points at Last

Music Wire Translation Pins - Blue Eagle Pins

Users of Music wire test fixtures have long suffered from false opens using poorly pointed music wire translation pins.

A new method developed by Chirish Technologies produces perfectly concentric points.

Music wire translation pins were introduced to PCB test fixtures as the density of circuit patterns increased. The screw machined pins in use were limited in length to less than 2.5 inches. The machined pins became cost prohibitive The SMD circuit layout made music wire translation pins a standard.

Machining methods for pointing the music wire translation pins, produced irregular points differing one end from the other as the material parted. Pins were polished or tumbled in an abrasive media to improve the surface finish of the points. As diameters became smaller than .5mm polishing became less effective.

As music wire pins became even smaller in diameter, the problem became critical. Test engineers were faced with ever increasing false opens with test machine throughput plummeting. A better pointing method had to be found. The price point of the .3mm and smaller music wire translation pins was driven down to a few pennies. Whatever the solution would be it had to compete at these levels.

In the US and Europe the solution to the problem was the moving probe test system. This solution was suitable for very high value and low volume PCBs. The solution was out of the question for high volume products, which often had he highest density circuit patterns.

Chirish Tech in partnership with CalChina in Ontario Ca. developed a method for producing concentric, uniform points with symmetry of both ends. These pins are produced in diameters as small as .2mm and are distributed under the brand name "Blue Eagle Pins"
