Circuit boards and the interface around them.
Chongqing Jingying brings together printed circuits, board assembly, membrane switches, printed control panels and metal nameplates. For a buyer developing an instrument or control unit, that combination puts the operator-facing parts and the electronics behind them in the same sourcing conversation.
Established in July 1998, the company describes its operation in Chongqing’s Caijia industrial area. Its English company introduction uses Chongqing Elite Circuit Board Co., Ltd.; its Chinese legal name is 重庆精英电路板有限公司. The business specifically describes coordinated development, processing and integration for customers whose parts would otherwise be bought separately.
Start with the front of the product.
Jingying’s graphic-panel range combines printed symbols, labels and display windows with the shape of a control surface. Its panel descriptions list PVC, PC and PET substrates and double-sided adhesive for attaching the finished overlay.
The numeric-keypad example and the red-and-green control-panel example show two different arrangements in this range. Artwork, the display or indicator opening and the attachment surface belong to the panel drawing; they are also the points where the panel must line up with the electronics and enclosure.
Metal nameplates form a separate catalogue range for product marking. They should be specified as their own component rather than silently substituted for a flexible graphic overlay.
A printed panel and a working switch are different parts.
Jingying lists membrane switches separately from graphic panels. Its switch description identifies a panel, upper circuit, spacer and lower circuit: pressing a key brings the circuit contacts together, and releasing it opens the connection.
For a panel-and-board project, the useful discussion concerns the switch layout and its connection to the controller. The button positions, tail or connector location and enclosure fit should be considered together. Jingying’s published integration work makes this a relevant enquiry; the catalogue examples here are separate items, rather than a claimed complete instrument built from these exact photographs.
The board, then the assembled electronics.
The company introduction lists single-sided, double-sided and multilayer PCBs alongside SMT processing and BGA soldering. Its combined circuit-board and soldering catalogue shows both bare circuits and populated boards.
PCB fabrication
Start a fabrication enquiry with the board drawing and intended construction. The photograph is a catalogue example; the single-, double- and multilayer service range comes from the company’s manufacturing introduction.
SMT and through-hole assembly
The published operation includes SMT and THT workshops. For this work, identify whether Jingying will buy the components, assemble customer-supplied parts or provide both. An assembly enquiry can include the membrane-switch connection as part of the drawing review.
For coordinated sourcing, show how the panel, switch and board connect in your product. Ask Jingying to identify the parts and assembly steps included in its quotation. The two shortlist options keep fabrication and component assembly visible as separate scopes.
Panel work and electronic assembly share the published operation.
Jingying describes a panel workshop, copper-clad board and nameplate etching, plus SMT and THT work. The official workshop gallery shows production workspaces alongside individual machines. The photographs below give a view of that setting.
The company’s introduction reports a 16,000 m² factory and more than 200 employees without a statement date. Those are published company-profile figures; available production time for a new project belongs in the quotation.
The Chongqing company behind the catalogue.
The contact page gives Building 20, No. 6 Fengqi Road, Caijiagang Town, Beibei District, Chongqing. The website’s business-licence image identifies the same company, a founding date of 16 July 1998 and unit 20-2 at that address.

Quality-system document and source dates
The newer certificate image on the website is numbered 25025Q10217R0S and names ISO 9001:2015, with dates from 22 January 2025 to 21 January 2028. Its scope covers circuit-board soldering and the production of PVC panels, membrane switches and nameplates. It is retained as the company’s published document, with issuer-status confirmation required for a contract that relies on the certification. The old ISO 9001:2008 wording in the introduction is not presented as a current certificate.
About this company profile
Company and product information was read from Jingying’s official website on 9 October 2026. Images retain their corresponding catalogue or workshop context. Product-specific dimensions, laminate grades and process limits are supplied through drawing review; the website’s general descriptions are not filled out with guessed specifications.
