MANUFACTURER DOSSIER
龙岩市武平县欣达电子有限公司 · Fujian
Singta’s company introduction separates its general single-sided, double-sided and multilayer PCB production from a quick-turn operation established in September 2014 for prototypes and small-to-medium batches. That service is positioned at 2–8 layers. A different process page publishes 1–10 layers, with 4–8 layers as its focus. These are two disclosures with different scopes, not two specifications for every pictured board.
Ask which service channel will review the files, where that order will be fabricated, and whether the repeat batch will use the same approved stack, material and inspection plan. A prototype approval does not by itself approve a changed production route.
The site advertises online ordering, payment and production-progress tracking. Agree whether the quoted clock starts after payment, complete files or signed engineering approval, and what pauses it. No current order, price or delivery commitment has been tested through that external system.
The existing 2–8-layer prototype service is retained. Its catalogue power-board illustration does not disclose that board’s actual stack or geometry.
The original manufacturing narrative has an inconsistent founding chronology: investment is placed in October 2004 but production is described as beginning on 2 January of the same year. The 2014 service expansion is a separate statement. Use the current production and contractual identity below rather than relying on a reconstructed founding date.
The product catalogue groups boards into medical, communications, security, power and industrial-control applications. The individual pages provide photographs and category titles, without a stack drawing, copper specification or measured test result. Below, each corresponding original image stays whole; an application label is not turned into a qualification.
Release voltage and insulation requirements, exact laminate, copper, creepage clearances and electrical acceptance for the drawing. Printed marks are not certification evidence.
Supply the stack, material grade, impedance structures and measurement requirements if applicable; agree a coupon and report rather than assuming the black mask establishes performance.
State the required drawing revision, laminate and lot traceability, workmanship class, testing and documentation. Medical category placement is not a medical-device qualification.
Provide outline datums, mechanical clearances, panel-breakaway requirements and finished-hole callouts. Do not estimate dimensions from the photograph.
Specify operating environment, copper, material grade, board thickness and the acceptance test. Confirm panel rails and depanelisation before committing the assembly fixture.
The industrial-control image also appears under security; another yellow-board image is reused in power and communications. Those repetitions are not counted as additional physical designs. Mask colour, printed marks and apparent pad density do not establish material, layer count, minimum geometry or product recognition.
These values come from Singta’s process page. They describe its published general route, not simultaneous limits or specifications for the five examples above. Obtain an engineering acceptance for the exact stack, copper and panel.
The table gives 0.2–6.3 mm drill diameters and says larger holes require separate treatment. It also states a minimum one-side annular ring of 0.153 mm (6 mil) for dense routing. Its exception for spacious locations is not permission to erase the ring requirement in a dense design.
The separate finished-hole row gives 0.2–6.20 mm and explains that plating reduces the hole diameter. Both lower limits being 0.2 mm does not prove a 0.2 mm drill produces a 0.2 mm plated finished hole. Confirm drill compensation, plating and the drawing’s finished-hole requirement.
The ±0.08 mm row calls the value a drilling tolerance, but its example describes a nominal 0.6 mm hole finishing at 0.52–0.68 mm. Ask which finished PTH, NPTH or drill measurement the agreed tolerance applies to. A connector fit needs an explicit finished-hole callout and acceptance method.
The Protel/DXP note asks for one outline layer, either Keepout or Mechanical, rather than conflicting outlines in both. Provide an explicit fabrication drawing and identify the controlling exported outline in the revision package.
The same note distinguishes Solder from Paste for mask openings; it says the Paste layer is not processed as solder mask. The PADS note requests non-metallised slots in Drill Drawing and describes Hatch-based copper-pour restoration. Ask CAM to acknowledge the intended outputs before production.
The source lists minimum legend stroke 0.15 mm and height 0.8 mm, with a stated 1:5 width-to-height ratio. Confirm legibility on the final mask colour and panel, including any assembly references required after depanelisation.
The table displays 0.1 mm, then explicitly says the company “temporarily does not make solder-mask bridges.” Bridge support remains unconfirmed. Send the pad geometry and mask artwork and obtain a written process decision; do not assume the numerical row guarantees a dam.
The table describes photosensitive solder-mask ink. It does not provide a named ink grade or a lot certificate. No installed laser-drill, LDI, flying-probe or impedance-test inventory is supplied by these pages; the introduction’s general “advanced equipment” wording is not converted into an equipment list.
The official contact page names 深圳市中显达科技有限公司, Shenzhen Zhongxianda Technology Co., Ltd. It publishes 0755-89715011 / 89715921, mobile 18665835473 / 13928408705, QQ 2853687145 and zhongxianda@163.com.
These are website-published contact details; mailbox control has not been tested. The older CRM QQ mailbox is not presented as a newly confirmed official address.
The same page names 龙岩市武平县欣达电子有限公司, at Buildings A07 and A08, Yanqian Industrial Concentration Area, Wuping, Longyan, Fujian. Production telephone numbers are 0597-4587818 / 4587828 and fax 0597-4587808.
For the purchase order, confirm the contracting entity, invoicing identity, producing site and responsibility for any subcontracted step. The introduction says Shenzhen Zhongxianda invested in the Wuping company; that disclosure is not a current ownership-register extract.
The undated introduction claims two standard factory buildings totalling 10,000 m², 350 staff and 150,000 m² monthly capacity. These figures are manufacturer statements, not measured current capacity or available production slots. Obtain the current site and schedule for the approved order.
The Fujian Department of Science and Technology’s 2025 second-batch registered science-and-technology SME list names 龙岩市武平县欣达电子有限公司 at row 810, PDF page 23, registration number 2025350824A8000996. This is a dated entity registration record. It does not establish current production capacity, ISO certification or acceptance of a medical product.
The introduction’s framed SGS ISO 9001:2008 photograph names DONGGUAN PINSHENG ELECTRONIC CO., LTD., with a historical validity period ending in 2016. It is not a certificate for the Wuping Singta company. The footer’s “ISO90001:2008” wording is also not treated as an issuer-verified credential.
CPCA and SPCA plaque photographs, customer logos and markings printed on catalogue boards are not substituted for a current certificate holder-and-scope result. Where an order requires UL recognition, a quality-system certificate or application-specific qualification, obtain the applicable current issuer record, producing-site scope and construction/model annex.
For FR-4, request the exact grade and controlled supply documents; “KB material” does not identify the supplied batch. For a medical-labelled reference, specify traceability and qualification requirements in the contract instead of assuming the catalogue label supplies them.
Reviewed 9 October 2026. One separately scoped prototype service and five original application references are selectable. Unknown sample values stay unknown; numerical general-process disclosures remain here with their qualifications.
Prepare a revision-controlled PCB RFQ →Manufacturer pages, all original catalogue images and the Fujian original list were reviewed separately. Repeated images are not new designs; application labels, historical plaques and a certificate naming another company are not current Singta qualifications.
