The eight layer test board is a 3×5 array with 15 component placements per board. The board is 132×77 mm in size, and 1.0 mm thick. The standard surface finish is OSP. Practical Components’ test vehicle is designed for the new TMV® 620 solder ball 0.4 mm pitch bottom component and the TMV® 200 solder ball 0.5 mm top component.
Both top and bottom components have a daisy chain pattern through the substrate of the part. A daisy chain pattern also runs through the test board. The design allows for daisy chain three net design, meaning both top and bottom components as well as the board can be tested individually or as a group. Additionally, the kit allows end users to test the integrity of their process applications for TMV® components.
Practical Components’ products are designed to help engineers qualify their technology, and train and grow their business while providing significant cost savings. Special attention is given to lead-free availability and formulations.
Dummy components are exact mechanical equivalents of live components used only when the physical properties of the components are required. These components can cost as much as 80 percent less than live components, making them ideal for testing solder processes, machine setup and other process evaluations.
