DES PLAINES, IL – PCB Libraries Inc. has released a free IPC-7351 land pattern calculator that reportedly generates results that match the LP Viewer library documentation.

The calculator is a scaled down version of the LP Wizard. It calculates CAD library parts that comply with the latest IPC-7351 revision. It relies on the data underlying the IPC standard, which includes fabrication, assembly and component tolerance-based mathematical algorithms.

IPC-7351 uses calculations that represent a change in the way land patterns are defined, developed and categorized. It is published by IPC, Association Connecting Electronics Industries.
 
“We’re pleased to be working with IPC in a unified effort to provide PCB designers worldwide with access to our IPC-7351 CAD libraries and LP Software tools," said Tom Hausherr, CEO and director of technology at PCB Libraries.

The SM321 pick-and-place machine is said to assemble up to 21,000 cph at ±50 µm accuracy, based on IPC-9850. It places QFPs and BGAs at speeds up to 5,500 cph at ±30 µm accuracy. Handles boards up to 20 x 24" at production speed. Comes with high-resolution flying vision system and enhanced board handling capabilities.

Has a low mass head mechanism with high speed motor to deliver a stable motion platform for consistent, on-target placements. The board transport system features an enhanced drive system with a flat handling system to safely move large PCBs and thin, flexible substrates. Is configured for Samsung SM Series slim format tape feeder system; handles EIA-481 tape sizes, and holds a maximum of 120 8-mm feeders. Tape feeder monitors inventory on the supply reel and notifies before replenishment is needed. A one-touch clamping feature permits users to replace tape feeders during operations, while the system's endless-discharge method for non-stop operation provides efficiency, reliability and repeatability of component pickups. Performs complete lot tracking and inventory management, and automatically optimizes placement sequence.

The SVS Ascent platform is for in-line, 3-D SMT inspection of solder paste depositions and component placement process control. Handles boards up to 20 x 24". Features an all-solid-state laser scanning platform with a reported 8 MHz data acquisition rate, all digital processing, and 8X oversampling. Analyzes data pixel by pixel, without merging or blending areas of acquired data. Said to permit panel setup from CAD data within 10 minutes and to detect flaws in volume, area, height, x/y position, coplanarity and bridging.
