Hysol QMI536NB non-conductive PTFE-filled paste is for stacked die applications that require extremely low stress and robust mechanical properties. Can be used on all levels of a stacked die, enabling the qualification of a single material. Is said to eliminate provide very low resin bleed and very fast cure. Can be used on solder resist, bare silicon and multiple die passivations. Is lead-free compatible, showing no reliability issues or material deterioration even when processed in higher temperature environments. shows high resistance to delamination and popcorning after multiple exposures to 260°C reflow temperatures.
PRO 2 Tdp is a tabletop assembly cell that may be used for low- to mid-volume manufacturing operations that require an LED component be picked, placed and soldered onto a PCB or substrate. The onboard dispensing head also can place a dot of thermal paste or silicon adhesive between the PCB and LED prior to attach. The robot selectively solders with twin irons attaching each side of the LED simultaneously. Dual automatic solder feeders, pre-heat plate and thermal loop feedback are standard.
Series 305 Horizontal Laminar Flow Clean Bench features a stainless steep table top with a white painted-steel shell, front access and interior lighting. Available for Class 100 or Class 10 environments.
Bench length and height depends on the specific process, but standard floor-to-tabletop height is 30 in. Standard widths are 2-1/2 in. over nominal 3, 4, 5, 6, 8 increments and the interior depth (interior table or working space) is 21.5 in. Overall cabinet width, depth and height will depend on the size of unit chosen.
Clean HEPA-filtered air flows outward from the cabinet. This horizontal laminar flow air washes out particulates and prevents contamination from entering the clean work zone. The cabinet features “clean edge” construction that puts the hood and tabletop in shear with the media edge of the HEPA filter to reduce turbulence along the sides of the hood, improve laminar flow and prevent contamination infiltration around the perimeter of the hood.
Top and bottom front grills recirculate the air within the bench. Provides recirculating temperature control to within ± ½ºF. Can operate at or above ambient using make-up air for cooling, or it can have an air conditioning unit with reheat for temperature control at or below ambient.
