MANUFACTURER DOSSIER
深圳市德群快捷电子有限公司 · Guangdong
深圳市德群快捷电子有限公司 · Dequn Quick PCB describes a Shenzhen-based quick-board operation established in August 2013, with FR-4 fabrication, laser-stencil services and SMT assembly. Its published design rules accept 1–10 electrical copper layers. The catalogue gives more specific examples: double-sided boards, four- and eight-layer boards, a six-layer half-hole board and a BGA board.
Gerbers, drill definitions, netlist, stack, copper, solder mask and profile. Identify which hole dimensions are finished values and which are drill-tool sizes.
Read the actual design rules ↓Supply the paste layers, board revision, frame and foil requirements. Ask for approval of reduced or modified apertures before cutting.
Separate stencil acceptance ↓Add a controlled BOM, placements, assembly notes and a test procedure. Specify whether the price includes components, rework and functional testing.
Define the assembly hand-off ↓The distinctions matter for a “quick-turn” enquiry: a fabrication lead time is not automatically the delivery time of a populated, tested board. Ask for separate engineering-release, material-availability and shipment milestones.
The official product page repeats a 4 mil line / 4 mil space entry and a 0.3 mm “via” entry alongside these examples. Those are manufacturer-published entries; they are not measured results from the pictured boards. The via wording does not define a finished plated hole.
Specify the mask ink, finished dimensions and finished plated holes on the fabrication drawing. Confirm whether the quoted geometry and mask openings can be delivered together.
Approve the stack and inner/outer copper before quoting. The green-mask title conflicts with the repeated white-ink paragraph; release the actual mask colour and ink requirement.
Send the edge-plating and routed profile drawing. Ask for the finished castellation diameter, annular land, breakout and burr acceptance; the generic 0.3 mm via entry is not a half-hole limit.
Release the package footprint, mask openings and assembly requirement. Confirm whether mask bridges are needed: the general service rule says they are not offered in the stated fabrication service.
Define the eight-layer stack, reference planes, finished copper and panel routing. Any impedance target needs an agreed tolerance, coupon and measurement plan instead of inheriting a general process limit.
The official explanation identifies this as the material cutting / working-panel size.
This is the separate customer-design guidance on the same page, subject to file review.
Send finished dimensions, panel rails, routing slots, breakaway method and quantity together. Do not quote a 1200 mm finished board from the working-panel headline.
Confirm the dielectric stack and copper distribution for a multilayer design. These separate rows do not establish that every layer, thickness and copper value can be combined.
The hole-tolerance row is headed mechanical drilling (±0.08 mm), but its explanation uses a finished-hole example. Ask for explicit drill-tool, plated finished-hole and non-plated-hole tolerances; the directory does not resolve that ambiguity by assigning a finished-hole minimum.
The fabrication rule distinguishes the solder-mask layer from the paste layer. That does not mean the paste layer can be omitted from a separate stencil or assembly order. Identify the deliverable before applying a bare-board instruction.
The manufacturer says it established the SMT laser-stencil division in 2018 and can modify aperture data. Agree foil thickness, frame, fiducials, paste type and aperture drawing revision. Its advertised 1 μm repositioning statement is not a supplied acceptance report for a finished aperture.
The SMT section describes three Panasonic placement lines, BGA/QFN handling, automatic and semi-automatic paste printing, a Jintuo N-800 eight-zone lead-free reflow oven, and wave/DIP work. It lists 0402 and 0201 without defining the package-code system. Specify the actual dimensions and manufacturer part numbers rather than assuming a size convention.
The same section names AOI and solder-paste thickness measurement. Those inspection methods do not by themselves establish functional testing. Ask for the actual inspection coverage, any X-ray/ICT requirement and the power-up or functional-test procedure included in the quote.
The equipment page’s Shenzhen description dates its procurement list to June 2016: drilling, PTH, plating, exposure, profiling and flying-probe equipment. Its quantities are historical manufacturer statements, not a current inventory or reserved capacity for a new order.
The contact page identifies the Shenzhen plant at Building 3, No. 48 Pingzi Road, Nianfeng Community, Pingdi, Longgang. The equipment introduction describes the headquarters and a nearly 5,000 m² quick-board base without a current dated capacity statement.
The contact page calls this the Shajing marketing department, at the first floor of Building 3, Haosi Western Industrial Park, Heyi Community. The equipment navigation instead says “Shajing factory”. Confirm whether your fabrication or assembly is actually performed there.
The contact page names a Guilin factory at Building 13, Jinjiping Industrial Park, Xinping, Lipu, Guangxi. The read pages do not establish the legal contracting entity or assign each pictured product to this plant. Request that allocation on the quotation.
The Shenzhen Science, Technology and Innovation Commission’s original 2023 first-batch proposed high-tech-enterprise cultivation subsidy list names 深圳市德群快捷电子有限公司 at row 6467, PDF page 127. The list is a proposed-subsidy record. It is not evidence that the payment occurred, a current certification check, or an approval of the PCB/SMT processes described above.
The official contact page publishes sc@dqkjpcb.com and telephone +86 755 89311909. They were checked against the website; no mailbox-control test or outbound message was performed. Keep the buyer enquiry in PCBVerified and ask for the named entity, producing address and agreed inspection documents.
Individually researched 9 October 2026 from the complete official pages, corresponding original catalogue photographs and the original government PDF. The repeated mask-colour paragraph and hole-definition ambiguity are retained as questions, not silently resolved. No numerical limits were inferred from images and no quality or certificate badges were assigned.
