The MGX B-52 Legacy 2 SIR test board evaluates the activity of flux residue at both the I/O and under component terminations. MGX B-52 Legacy 2 is used to characterize solder paste, process development, and process control. The B-52 Legacy 2 card is one of our most popular test cards.
The MGX B-52 Legacy 3 test board is designed to detect inadequate rinsing and aged wash chemistry when cleaning production assemblies. The QFP 80 and QFP 160 in Quadrants 3 and 4 have SIR comb patterns located under the component termination.
