ACT200
ACT200 ultra miniature surface mount Watch Crystal with power consumption making ideal portable applications. small footprint renders suitable high density circuit boards applications where space limited. tape reel packaging means that ideal automatic placement machines (loose product also available). heart device heat resistant cylinder type crystal which provides high stability characteristics sufficient allow reflow soldering.

ACT200 TAPE REEL
SOLDERING WATCH CRYSTALS
Reflow oven should emulate better maximum reflow profile shown diagram below. Note just important conform times given well temperatures. Pre-heat should exceed 180°C ±5°C Maximum time 120s Peak soldering temperature should exceed 260°C. Time peak temperature should exceed seconds. Total reflow time above 120°C should exceed minutes.
WASH PROCESSES WATCH CRYSTALS
order achieve optimum performance plastic packaged watch crystals plastic normally used polymer plastic which porous. With some wash processes (Involving total immersion unit) moisture ingress causes impedance across internal crystal unit connections stop oscillating. time (shortened drying process) crystal will recover original characteristics. performance with regard damp heat (humidity) effected this plastic. Devices using epoxy plastic option overcome this problem should cause inconvenience. this type package increasingly becoming more difficult obtain environmental problems with epoxy plastics.
