Components Procurement
China Dragon offers a wealth of experience in offering final box build assembly.
Our extensive range of services in manufacturing PCB’s, PCB Assembly, cable preparation and cable harness manufacture, in addition to many other associated services, leads to the inevitable conclusion of us combining all of these component parts in a complete tested ‘ready for market’ solution.
Box build can be simple enclosures housing PCB Assembles, to complete Sub-Assemblies / Backplanes / Power Supplies enclosed in a bespoke housing with HMI Interface. Our experience and trained staff are able to put together a solution to meet your needs.
 Box build is ultimately about attention to customer detail, and proficiency in a multitude of tasks to pull together a final product. Also crucial is a network of partner companies to ensure our customers can receive a one stop solution from China Dragon. We believe we are ideally placed to provide these attributes.
For further information on final assembly and box build please do not hesitate to Contact us via phone email or Skype where we will ensure our highly trained team can assist.
Quality Assurance
 China Dragon is conscious that its reputation for high quality PCB assemblies needs to be continually maintained and enhanced. Our commitment to quality therefore is all encompassing throughout the business. Our staff are our finest asset and most of them have a wealth of PCB assembly experience gained over many years of service. We understand, however, that ongoing improvements are not only necessary but also vital to our continued success. To this end China Dragon staff undergo continuous “in-house” and external training to IPC 610 standard. Specific equipment training is regularly assessed and improved where necessary.
Our facility has attained ISO 9001:2008 accreditation as well as a number of customer specific approvals.
Our products are quite varied in how they are assured for quality before anything leaves for the customer. To this end we have a range of methods and systems used.
 Automated Optical Inspection / AOI
China Dragon employs made (and indeed locally made) Easy Vision Automated Optical Inspection (AOI) Systems for all surface mount assembly prior to passing onto the next stage of assembly. These systems allow us to perform:
- First off checks to ensure validity of automated assembly programme.
- Polarity and positional accuracy checks for all components.
- Solder inspection & validation.
- Statistical analysis of assembly defects to assist continuous improvement programme
- Serial numbering and batch control.
 Automated Functional Test
Test fixtures used can either be designed and manufactured by Jinghon in conjunction with our design team or supplied by our customers. They are a vital part of our QA strategy and allow us to check as much as possible the full validity of a product before it leaves us.
Assisted Visual Inspection
Not all products allow for the use of a full test. To this end we have highly skilled personnel using a range of Vision Engineering equipment i.e. Mantis, Lynx Microscopes etc. these allow us to perform detailed inspection for component accuracy and solder inspection.
