Capability Overview
PCB Prototyping Up to 25 Boards
As a PCB assembly supplier, we use the same in-house expertise and resources to prototype PCBS in limited quantities, up to 25 printed boards. Our prototyping team consists of welding technicians, surface mount process engineers and parts purchasers.
Parts from Premium Distributors
Our supply team can source your parts from premium distributors, including outdated or hard-to-find components.
Boosts Production Efficiency
The time-saving advantage of the supply team alone provides convenience to customers and increases production efficiency.
Optimize Packaging to Reduce Costs
At the request of our customers, our electronic prototyping team will optimize packaging types such as bulk, tubular or tape to reduce the cost of orders with limited bills of materials.
Prototype PCBs with Parts Kits
When needed, we can prototype our customers' PCBS using parts kits.
Cross-Reference & Replace Parts
In addition, we can cross-reference parts or components when your specific type is not available, and all component replacements are approved by the customer before they are ordered or used in the assembly process. Customers are always retained in addition.
Zhongyilong is a Chinese prototype PCB assembly supplier
Zhongyilong is a Chinese prototype PCB assembly supplier and a global expert in cost-effective prototype PCB assembly services. We have an in-house team of experienced experts who can take a customer's PCB design from the parts procurement, prototyping and assembly stages to the final prototype product, which can usually be shipped within four weeks if all supporting documentation is correct and there are no supply chain hurdles.
Service Process
PCB Manufacturing
Our prototype PCB assembly service process enables customers to obtain even more complex designs using our highly reliable Design Manufacture (DFM) and Design Test (DFT) services, which guarantee that prototypes are built to your specifications in a quality-controlled manner.
Prototype Assembly
As a prototype PCB assembly supplier, we have developed assembly facilities specifically set up for prototype assembly orders. These special facilities have the flexibility to allow the use of manual and/or automatic component loading stations. Our facility is capable of handling fine-pitch parts and ball grid arrays on high-density FR-4 boards.
PCB Manufacturing
On-time delivery is a value we share with all our customers. We work together to communicate with our customers about any engineering, parts or process issues. However, the electronics assembly process usually takes about two weeks.
Deliver On Time
After the staff of ZhongYilong reviewed the customer's engineering documents and solved all the parts procurement issues, the PCB manufacturing began after all the components were purchased.
