CG selects a quality-assured and reliable process for each requirement of fine glass powders. The fine glass powders are used for coating of electronic components, insulation materials, electronic devices, circuit boards and bonding of semiconductors by stable particle size control and reliable glass composition control. Some are used as a material of thick film pastes for LTCC, MLCC, inductors and PDP (plasma display panel).
Example for products of solar sell silver paste glass. Below shows the properties.

CG is committed to seeking competitive prices and high quality products for customers. We have rich experience on composition of glass powder, coefficient of thermal expansion, control of particle size and softening point, etc. and also we have strong management of information security including the implement of Non-disclosure agreement (NDA). Therefore, we look forward to cooperation and partnership with your company as a second supplier or an OEM supplier.
1.Confirmation of specifications
We discuss well with our customer to identify requirements and specifications through analysis of glass composition, distribution of particle size, selection and trial production of samples with quantity and desired cost at mass production. For example: we will provide several lab samples (30-100 gram each) for user evaluation at the first step.
2.Pilot production test
We remake the same glass powder at different process of mass production scale when the specification of lab sample has been confirmed by customer.
3.Mass production test
We select the best manufacturing process for mass production depended on the quantity (several hundred grams to several tons per month) and composition of glass powder. We also check the cost of materials and production and discuss well about what is the best choice with customers.
We persist in stable manufacturing and strict quality control according to contracts regarding ordering method, ordering unit, delivery date, inventory, price, payment site, etc.
It is a contract to define confidential information. We carefully discuss and conclude regulations, restrictions, confidentiality obligations and remedies with individual customers.
