Servo-Flo 488 two-component fixed-ratio meter-mix dispense system is l for automated or manual high-volume dispensing applications. The servomotor design is ideal for manufacturers wanting one system to dispense small, medium and large volumes of a mixed material for different-sized part batches or extruded bead sizes.
 
The positive rod-displacement meter system can be used as a shot meter from 3 to 1400 cc and as a continuous-flow dispensing meter for infinite volume sizes of two-part epoxies, urethanes, silicones and acrylics. The servomotor design provides fixed-rate or variable-flow rate profiling, which varies the dispense rate on-ratio as needed to optimize filling operations, meet bead-diameter requirements and automation tip-speeds.
 
Three levels of operator interface controls handle any meter-mix production-dispensing application. Operator-interface control quickly sets output flow rates and adjusts material-volume settings. The automation or the operator can select different stored-flow and volume programs for different product-dispensing requirements.
 
Accepts low- to high-viscosity materials and is supplied by pumps or pressure tanks. Can be floor-mounted, portable-cart mounted or enclosed in a cabinet with many dispensing features.

AGI Corp. is producing titanium selective solder pallets for wave soldering applications, including PCBs with PTH components in close proximity to bottom side SMDs. Machining titanium vs. composites achieves ‘seal walls’ down to .020” thick (and.015” over short distances). Other benefits: no sagging during soldering and thinner floor thickness which reduces the “z” height solder must travel.
 
Based upon machining a single piece of titanium to match the PCB and incorporating that into a composite pallet frame. Does not use small titanium inserts screwed to the pallet, which avoids leaking, alignment and thermal mismatch. Composite frame runs cool, so it is easier to handle or convey after soldering.
