Milestones
Yuhchang was established on April 28, 1967 with capital of NT$ 4 million (US$ 100,000), and began to manufacture chargeable lights, emergency lights safety lights for mine use, and concrete liquid battery.
Capital increased up to NT$ 6 million (US$150,000), we imported foreign advanced technology to produce high & low voltage capacitors.
Capital reached to NT$ 10 million, and the company was certified as a qualified factory by Taiwan Power Company.
The company was rated grade A in terms of qualified exporter and quality control factory by Merchandise Office of Economic Association (MOEA). Taipei branch has been established since.
High & low voltage capacitors were granted the No.2845 and 2846 CNS Mark by Central Standard Department. Kaoshiung branch has been established since.
With increasing capital of NT$19 million (US$ 500,000), square type capacitors used for electrical apparatus were successfully developed.
With capital of NT$ 30 million (US$ 750,000), MF low voltage capacitors were successfully developed.
Capacitors for induction cookers and microwave were developed.
