This section establishes visual acceptability criteria for the installation of discrete wires jumper wires. The following items are addressed: A jumper wire 25 mm [0. Jumper wires are considered as components and are covered by an engineering instruction document for routing. Keep jumper wires as short as practical and unless otherwise documented do not route over or under other replaceable components. For the sake of simplicity only the more common term. Design constraints such as real estate availability and minimum electrical clearance need to be taken into consideration when routing or staking wires.

Burns Defect — Class 1. There are many new photographs of X-ray or endoscope illustrations to identify some of the characteristics that the industry is experiencing in the implementation of BGA assembly processes as well as void process indicators. The tool also allows for modification of dimensional attributes of IPC approved land patterns. The standard provides printed board designers with an intelligent land pattern naming convention, zero component rotations for CAD systems and three separate land pattern geometries for each component that allow the user to select a land pattern based on desired component density.

The revision also discusses the usage of thermal tabs and provides a new padstack naming convention that addresses the shape and dimensions of lands on different layers of printed boards. For customers and manufacturers, it seems like every company has a unique way of calculating defects and then reporting on quality.
