What is a multilayer printed circuit board?:
A Multilayer PCB is a sophisticated circuit board integrating three or more conductive copper layers, separated by insulating core substrates and prepreg sheets, then laminated into a single rigid structure via high-temperature and high-pressure processes. Its layered design enables intricate 3D signal routing through precision vias, minimizing electromagnetic interference and crosstalk.
Basic Characteristics:
| Characteristic Category | Details |
| Core Structure | 3+ conductive copper layers separated by insulating core substrates and prepreg sheets; bonded into a single rigid structure via high-temperature & high-pressure lamination |
| Signal Routing | Intricate 3D routing with precision vias (plated through-holes, blind/buried vias); reduces signal path length |
| Key Advantages | Minimizes electromagnetic interference (EMI) and crosstalk; optimizes device footprint; supports dedicated power/ground planes |
| Typical Applications | High-speed electronics (5G devices, automotive ECUs); miniaturized equipment (smartphones, medical implants); |
FAQ:
1.Q:How many layers can your circuit boards provide?
A:We typically provide 1-30 layer boards, and in special cases, we can stack more layers.
2. Q:Do your circuit boards support customization?
A:Yes, we support customized designs. You can send us your Gerber files and BOM list, and we will provide you with an accurate quote based on the information and market conditions.
3. Q:What do Gerber files typically contain?
A:Normally Gerber files Include:PCB Types,Product thickness, Ink color, Surface treatment process and If SMT processing is required, component BOM and tag drawing are also required.
4. Q:What is your minimum order quantity for PCB boards?
A:Our minimum order quantity is 1 piece(5 square meters),the larger the quantity, the bigger the discount.
5. Q:Do you have relevant certification certificates to support this?
A:We hold numerous important certifications, including ISO, UL, CE, and RoHS. All products undergo rigorous quality testing.
6. Q:What payment method do you usually use?
A:For small orders, samples, or urgent payments, we accept Western Union. For large orders, we recommend T/T, which ensures the safety of both parties.
