Introduction of Low temperature co-fired ceramic PCB
LTCC ceramic substrate technology is a three-dimensional integration technology for complex microwave and digital circuits using new ceramic materials and microwave thick film integration technology. With the rapid development of monolithic integration technology, the integration of active devices is getting higher and higher, reaching unprecedented levels, which makes the integration of passive devices very important. LTCC technology can meet the integration requirements of passive devices such as resistors, capacitors, inductors, filters and couplers.

Compared with other PCB technologies, LTCC PCB has many advantages
1. Ceramic materials with high frequency, fast transmission speed, through-bandwidth excellent characteristics, increasing the flexibility of circuit design.
2. Can adapt to the requirements of high current, high temperature resistance, and better thermal conductivity than ordinary PCB circuit boards. Greatly optimize the design of electronic equipment heat dissipation, high reliability, can be applied to harsh environments, extending service life;
3. Can make high level number of circuit boards, can embed multiple passive components, further reduce the volume and weight ，it can save the cost of component packaging.
4. Good compatibility with other multilayer wiring technologies, which can achieve higher assembly density and better performance of mixed multilayer substrates and mixed multi-chip modules;
5. Intermittent production process, to facilitate the quality inspection of each layer of wiring and interconnection holes before the production of finished products, to improve the quality of multilayer substrates, shorten the production cycle and reduce costs.
6. Energy saving, material saving, green environmental protection has become an unstoppable trend in the development of the components industry. LTCC also caters to this development, minimizing raw materials, waste and environmental pollution caused by the production process.
FAQ
Q1. What documents do you need to prepare if you want to get a quote from us?
A: PCB boards need to prepare Gerber files, including RS274X, ODB++, DXF, PCB, PCBDOC and other formats.
For PCBA (PCB with soldered components), in addition to the files of PCB, you also need to prepare BOM list (component list), Pick and Place file (txt format), physical sample drawing or 3D PDF version file, etc.
PCB layout requires a PCB schematic and PCB outline drawing.
For PCB design, you need to express your ideas and we will discuss whether we can implement your ideas.
Q2. Do you have a minimum order quantity?
A: We have the flexibility to handle both small and large volume production. We do not have any minimum order quantity, and the smallest order we accept is 1 piece.
In general, the higher the quantity produced, the lower the unit price and the longer the delivery time.
Q3. How can we keep our product information and design documents confidential?
A: Your files are completely safe and secure. We protect the intellectual property of our clients throughout. All files from our clients are never shared with any third party.
Q4. How long is the delivery time?
A: The production time for standard PCB samples is 1-7 days, 7-10 days for small batch production, and 12-25 days for large orders.
For the production of non -standard PCB and PCBA, please send the reference file and production requirements to sales@pcbfactorysmt.com，we will reply to you as soon as possible.
Q5. What are the main products of your PCB / PCBA service?
A: Industrial control, automotive, medical equipment, communication electronics, aviation, LED...
Q6. How long does it take for PCB and PCBA quotation?
A: PCB quotation can be completed within 0.5-2 hours PCBA depends on the number of components, simple can be completed within 6 hours, complex 12-36 hours can be completed.
Q7. Shipping fee?
A: Usually we offer EXW, FCA, FOB, CIF and DDU terms, if there is no special request, the default terms quoted are FOB Shenzhen. Please mention the terms and conditions when you have any request.
We work with courier companies including DHL, FedEx, UPS, TNT and EMS, with air and sea freight also optional.
Shipping costs are determined by the destination, weight, and package size of the shipment. If you need us to quote the shipping cost, please let us know.
Q8. Do you accept process materials from customers?
A: Yes, we can source components and we accept components from our customers.
