Surface copper thickness measurement technology

・Control the key process of reducing copper wire before/after, electroplating before etching and other key processes to control the surface copper thickness
・Automated application to reduced human factors or without vertical point-taking measurement
・Micro-resistance technology with position and contact pressure control feedback
・Measurement accuracy: ± 3% (standard film)
・Measurable chemical copper: 0.25um~12.7um
・Measurable electroplating copper: 2.5um~300um
・It can be combined with job order, data feedback and upload
