SMT 88UH reportedly can be underfilled at room temperature without preheating substrate. Advantages reportedly include void-free underfill, easy rework, easy dispensing, outstanding reliability, and excellent mechanical resistance. Can be stored in a regular refrigerator or freezer. Can be used for chip-scale packaging, ball grid array devices, package-on-package, land grid array, and certain flip-chip applications. Suitable for bare chip protection in memory cards, chip carriers, hybrid circuits and multichip modules.

VuData statistical process analysis software for YesTech automated optical inspection systems stores data with all faults related to assembly numbers, board serial numbers, system operator and time. Collects performance data in terms of line speeds, timing and throughput. Generates comprehensive reports showing yield rates in both board and opportunity format, as well as current and historical failure rates with types and trends. Management reports are also available for inspection and review timing, false and genuine fault rates and other line metrics. Live charting directly shows yields and part failure rates, with common failures and rankings. Generates and emails performance alarms. Exports to Excel, pdf, jpg or other formats. Fail pictures presented in a fault picture viewer, and any data can be used to generate live charts, graphs and reports as circumstances demand. AOI performance can be tracked through reports related to time, user, board, fault, false call, assembly, job and serial numbers. Data can be searched, sorted, filtered and grouped without need for external software. Provides yield and throughput monitoring as well as other management statistics.
