Over a period of time, QFlex has developed capability to make extremely small form factor parts. Prototypes are cut with laser, volume production is done on class A zero clearance die. Some parts are less than half the size of a grain of rice with micro vias and very small pads. With our 23 watt custom designed UV laser, we can make extremely small openings in coverlay. With this high precision laser ( 2 micron beam size) it is possible to get 4-5 mil diameter holes in coverlay.
