McDry MCU-401 Hepa Filter is for precision measuring instruments, electronics components, or other materials that require a cleanroom and low humidity environment. Meets cleanroom Class 1000 specifications. Using a fan circulation system, dry air passes through the hepa filter and is circulated throughout the cabinet and back down into the drying unit. Is said to maintain relative humidity inside the cabinet below 10%, and can hold up to 50 kg (approximately 110 lb). Comes with digital meter that displays the RH level at all times. Features adjustable stainless shelves and is equipped with a high resistance ground terminal.

NL930 Pb-free, no-clean solder paste is said to feature good solderability, improve stencil life and provide superior cosmetics, especially when using SN100C. Offers print consistency with high process capability index and wetting characteristics. Post-reflow flux residues are penetrable. Is compatible with SN100C and SAC alloys with Type 3, 4 and 5 solder meshes, and with OSP, ENIG, immersion silver, and immersion tin finishes. Features high-volume repeatability with 16 mm pitch QFP pads and 12 mm circles, as well as good response to one-hour pause after two knead strokes at 35-65% RH.
