The common cause - A short to ground This is caused by a short to ground somewhere in the net controlling that segment. Since all 6 digits are wired as indexed common anode, there is only one “low-side” net for each segment and it's common to every digit. The following sections describe trouble-shooting and repair for each segment. text/html 2009-11-10T20:22:55-05:00 Kevin Bralten http://wiki.spiffie.org/parts:packages:gullwing_leads Gullwing Leads Leads that protrude out, bend down, then go out again are called gullwing leads. These are typically seen on surface mount parts to reach from the device's midpoint to board surface level and still provide a lead for soldering.

QFP packages are usually the package of choice for chips with more than 2-dozen leads, although QFN and BGA packages are becoming very popular. text/html 2009-11-10T19:55:01-05:00 Kevin Bralten http://wiki.spiffie.org/parts:packages:pqfp Plastic Quad Flat Package (PQFP) is a general term for a QFP device that is plastic; as this encompasses most other classes of QFP device, it's generally used to refer to a thicker (≥2.0mm) package or to refer to an uncommon package. As the term is much less definitive than, say, TQFP, check the mechanical drawings. text/html 2009-11-10T18:46:49-05:00 Kevin Bralten http://wiki.spiffie.org/parts:packages:lqfp A Low-profile Quad Flat Package (LQFP) is similiar to the common TQFP, but thicker (typically 1.4mm). It's a member of the QFP - Quad Flat Package family.

The tag line was ”Brilliant color when you need it, free black ink when you don't.”. This is done by including some black sticks in each color package. This results in 1.5x to 2x as much “free” black ink as color when you buy all three colors. If you didn't buy enough color, you could order additional cases of black for free from Tektronix.
