Key Attributes |
DPC |
Thin Film |
Thick Film |
|
Conductor Electrical Conductivity |
Very good. Thick copper conductor. |
Poor conductivity due to very thin film thickness. |
Good conductivity. Lowered by the presence of the glass phase. |
|
Via Electrical Conductivity |
Very good. Vias filled with pure copper. |
Very good. Vias filled with pure copper. |
Poor. Vias filled with 50% metal and 50% glass or pores. |
|
Feature Resolution |
Goood. Depends on Cu thickness. |
Very good. |
Goood. Determined by screen print capability. |
|
Cost |
Low to moderate. Vias and metal deposited in the same process. |
High cost. Expensive substrate. Lapp and polish required after via deposition. |
Low to moderate. Expensive metal pastes. Low cost substrate and low cost deposition technology. |
|
Thermal Performance |
Very good. AIN or alumina substrate and high thermal conductivity metal. |
Good. AIN or alumina substrate. Metal layer too thin for heat spreading. |
Moderate. Alumina substrate. Conductivity through the metal is poor due to the glass phase. |
|
Suitability for Power Applications |
Very suitable. Copper conductors carry high currents. |
Not suitable. Thin film layers can not carry high currents. |
Suitable. Conductors with a glass phase have moderate conductivity. |
|
Suitability for High Frequency Applications |

1:What products and service can you offer us?
Answer: With the development more than 20 years, now we have 6 business division and we are supplying Quartz Glass (Tube, Rod, Plate and customized parts), optical glass and cuvette, and also various precise ceramics,porous ceramics and refractory ceramics. We have the full processing line for ceramic thick film resistors, far infrared ceramic glass heating panel, quartz tube/ceramic plate ozone generator,porous metal fiber felt and polyester fiber cotton products. For all the products, we can design and customize according to the clients' demand.
2: Before mass order, can you offer samples? How will you charge for them?
Answer: We are willing to offer samples to lower your purchasing risk. Generally, if from inventory, we can deliver out within 3days, however if need processing, we can deliver out within 15days. For some difficult items, the delivery time will be decided by its grade of difficulty. For some low value items, we can offer free sample, however we would like you to afford the freight cost. For customized products, we need to charge the developing cost.
3: What test report or certificate can you offer? What achievements have you made in research and development?
Answer: Till the end of 2021, we have passed many ROHS, CE, MSDS tests and also the ISO9001 authentication. We have 8 registered trademark and 25 patents. Also we won the title of China High-tech Enterprise and Jiangsu Private Science and Technology Enterprises.
4: Do you have any agent in our area? Can you export your products directly?
Answer: Till the end of 2021, we haven't authorized any company or person as our regional agent. From 2008, we have the export qualification and professional export team, and till the end of 2021, we have exporting our products to more than 108 countries and regions, and our clients can contact us and purchase our products or service directly.
5: If the quality can not meet the requirement or any loss during the freight, how should we do?
Answer: We have strict QC test and professional QC team. We are always offering qualified products. If anything goes wrong, the quality can not meet requirement on the contract, we will reproduce the qualified products or refund the payment. We have the professional packing team and will pack the product in safe package for long distance delivery. If any loss during the freight, we hope you can assistant us to claim from the logistics company and we will arrange the replacement accordingly.
