COMPANY ENTERPRISE PROFILE
Established in May 1997, DISHA Elektronics specializes in the production of high-density PCB. It is administrated by highly skilled PCB professionals. At the beginning of 2015, in order to provide Indian customers with high quality PCB at better price, the owner tied with a new factory in JIANG XI province of China, where there are many conducive environmental facilities, cheaper hydropower and labour. This puts us at an advantage to control the cost and gives competitive edge.
Our quick turn prototype production allows us to provide short lead time and world class customer service at the same time, batch quantity production in Jiang Xi helps us minimize labour cost and maintain high quality
Our factory in China has IS0-9001:2008 and UL Certification. With more than 500 employees, it is growing and the latest manufacturing facility has a capacity of more than 15,000 square meters of double-sided PCB boards and 10,000 square meters of multilayer PCB boards per month.
This Plant in China is serving our customers all over the world and gaining their satisfaction.
Our mission is to provide dependable PCB service and best price for INDIAN customers. DISHA is continuously improving our capabilities and processes to reduce operational costs and improve PCB quality.
