For similar reasons, a technique called trace necking reduces (or necks down [7] [8] [9]) the width of a trace that approaches a narrower pad of a surface-mounted device or a through-hole with a diameter that is less than the width of the trace, or when the trace passes through bottlenecks (for example, between the pads of a component).
PCB via current capacity chart showing 1 mil plating via current capacity & resistance versus diameter on a 1.6 mm PCB. In printed circuit board (PCB) design, a via consists of two pads in corresponding positions on different copper layers of the board, that are electrically connected by a hole through the board.

Signal Integrity (SI) in PCB design refers to the quality of electrical signals as they travel through traces, vias, and components on a printed circuit board. Ensuring good signal integrity is critical for high-speed and high-frequency designs, as poor signal quality can lead to data errors, signal distortion, and system malfunction.
The PCB is clamped, and the nozzles pick up individual components from the feeders/trays, rotate them to the correct orientation and then place them on the appropriate pads on the PCB with high precision. High-end machines can have multiple conveyors to produce multiple same or different kinds of products simultaneously.
Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.

CADSTAR spans schematic capture, variant management, placement, automatic and high-speed routing, signal integrity, power integrity, EMC analysis, design rule checks and production of manufacturing data. Originally developed by U.K. PCB vendor Racal-Redac, CADSTAR has been part of the Zuken product portfolio since its acquisition in 1994. [1]
