Here are some images of machinery and equipment used in crystal product manufacture and test.
A vacuum/heat process, used to plate silver or gold electrodes onto crystal blanks
Prepared crystal blanks are mounted onto substrates for surface-mount products
Automatic tacking of package lids prior to seam welding surface-mount products
Oscillator final adjustment equipment. Oscillator units are adjusted to final frequency under computer control.
Resistance weld chamber. Crystals and oscillators are sealed under a controlled atmosphere. Units are 'back-filled' with nitrogen during the hermetic sealing process
Final sealing and test procedures under controlled conditions during filter production
Automated quality control equipment
