Rogers offers liquid cooling materials designed to dissipate large amounts of heat, and provide thermal management of high-power laser diodes and other heat-generating optical devices. The cooling structures are copper foil channels bonded into a tight block, with aluminum-nitride (AlN) isolation layers added for extra performance.
Smartsheet is a software as a service (SaaS) offering for collaboration and work management, developed and marketed by Smartsheet Inc. It is used to assign tasks, track project progress, manage calendars, share documents , and manage other work, using a tabular user interface.
Bare die supplied without a package. It is mounted directly to the PCB using bonding wires and covered with a blob of black Epoxy. [22] Also used for LEDs. In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a mold containing the LED(s) and cured. The mold forms part of the package. COF: Chip ...
The resist material protects the copper from dissolution into the etching solution. The etched board is then cleaned. A PCB design can be mass-reproduced in a way similar to the way photographs can be mass-duplicated from film negatives using a photographic printer. FR-4 glass epoxy is the most common insulating substrate.
A coupon or test coupon is a printed circuit board (PCB) used to test the quality of a printed wiring board (PWB) fabrication process. Test coupons are fabricated on the same panel as the PWBs, typically at the edges. Coupons are then inspected to ensure proper layer alignment, electrical connectivity, and cross sectioned to inspect internal ...
Besides the commercial vendors there are plenty of free GDSII utilities. These free tools include editors, [ 3 ] [ 4 ] [ 5 ] viewers, [ 6 ] utilities to convert the 2D layout data into common 3D formats, [ 7 ] [ 8 ] utilities to fly through a 3D version, [ 9 ] utilities to convert the binary format to a human readable ASCII format [ 10 ] and ...

Hardware design (i.e. mechanical drawings, schematics, bills of material, PCB layout data, HDL source code [2] and integrated circuit layout data), in addition to the software that drives the hardware, are all released under free/libre terms. The original sharer gains feedback and potentially improvements on the design from the FOSH community.
