In the process of electronic product development, PCB proofing is an important link. With the advancement of technology and the increase in market demand, rapid PCB prototyping services can greatly improve the speed of product launch and competitiveness. So, what does PCB board rapid prototyping service include?
Engineering review services
In the early stages of PCB prototyping, engineering review services are essential. Engineering review services involve professional engineers reviewing design drawings to ensure they meet design specifications and manufacturing requirements. Through early design and engineering review, errors in subsequent production can be reduced, costs reduced, and the overall development cycle shortened.
Material selection and procurement services
Material selection is one of the key links in PCB prototyping. Different electronic products have different material requirements. It is necessary to select the appropriate base material, copper foil thickness and surface treatment method according to the specific application scenario. Common substrates include FR-4, aluminum substrates, and high-frequency materials. Rapid prototyping service companies usually provide inventory of various materials to meet the needs of different customers.
Manufacturing services
1. Pattern transfer: Coat a layer of photosensitive material (such as dry film or wet film) on the copper foil, then use UV light or laser to expose the pattern, and then remove the unnecessary parts through the development process.
2. Etching: Remove excess copper foil through chemical solution or plasma etching technology, leaving only the required circuit pattern.
3. Drilling and plating: Drill various required through holes and blind/buried holes on the board, and then conduct electroplating to ensure the conductivity of the hole wall.
4. Lamination and lamination: For multi-layer boards, each layer of circuit boards needs to be glued together with resin and pressed under high temperature and high pressure.
5. Surface treatment: In order to improve weldability and prevent oxidation, surface treatment is usually performed. Common treatment methods include HASL (hot air leveling), ENIG (gold plating) and OSP (organic coating protection).
sting and inspection services
1. Performance testing: Use a flying probe tester or test stand to test each electrical connection point on the circuit board to ensure that continuity and insulation meet design requirements.
2. Appearance inspection: With the help of a microscope or automatic optical inspection equipment (AOI), strictly inspect the appearance of the PCB board to discover and correct any defects that may affect performance.
3. Functional testing: Some more complex circuit boards also need to be functionally tested to simulate the actual use environment and test whether their working performance meets expectations.
Packaging and shipping services
PCB boards that pass testing and inspection need to be properly packaged to prevent damage during transportation. The packaging provided by rapid prototyping services usually includes anti-static packaging, shock-proof packaging, and waterproof packaging. After packaging is completed, the proofing service company will quickly deliver the products to customers through express delivery or dedicated logistics to ensure that the research and development progress is not affected.
Technical support and after-sales service
Rapid PCB prototyping services not only provide production and manufacturing, but also include comprehensive technical support and after-sales service. When encountering problems or uncertainties during the design process, customers can contact the technical support team at any time to obtain professional guidance and advice. Even after the product is delivered, if customers encounter any quality problems or require further optimization, the after-sales service team will respond quickly and resolve them, ensuring customer satisfaction and trust.
PCB board rapid prototyping service covers many aspects from project review, material selection, production and manufacturing to testing, packaging, delivery and after-sales service. The efficient execution and seamless connection of each link can not only greatly improve R&D efficiency, but also reduce production costs and improve product quality.
