Yangzhou Juyuan Electronics Technology Co., Ltd.

Start with the contact system, not a multilayer capability headline.

Yangzhou Juyuan Electronics Technology Co., Ltd. · 扬州聚元电子科技有限公司 describes a business established in September 2011 in Fanshui, Baoying County. Its published range centres on single-sided boards, single-/double-sided photo-imaged boards, carbon-film and nickel-plated carbon-film boards, controllers and LED backlight constructions. The English site specifically identifies remote controls and household appliances.

This is a useful shortlist for the board types above. The reviewed catalogue is not a numerical HDI, controlled-impedance or multilayer process table. For those requirements, request a specific engineering proposal rather than interpreting a product photograph as a fabrication limit.

A remote-control board needs a contact acceptance plan.

Nickel-plated carbon-film remote-control PCB

Nickel plating and carbon film; remote-control example 1

Specify contact artwork, carbon ink, nickel coverage, resistance and keypad life. The catalogue does not state numerical acceptance values.

Select this board route →

Peelable blue-mask carbon-film board

Carbon film with peelable blue protection

Mark protected areas and removal timing. Agree the cured ink resistance, adhesion and compatibility with soldering and cleaning.

The catalogue also has three other nickel-carbon remote-control photographs. They illustrate additional layouts, not three extra independently established performance levels. The page uses the complete paired originals; no contact dimensions or ink thickness are estimated from their pixels.

Silver-paste filling is a specific route to quote.

Juyuan names two separate examples “double-sided silver-paste filled-hole board”. Their explicit two-sided construction is retained below. The title does not define hole size, fill composition, via resistance or endurance; those are order requirements.

Double-sided silver-paste filled-hole PCB

Double-sided construction; silver-paste hole filling

State via resistance, thermal cycling and soldering exposure. Silver-paste interconnection should not be silently specified as conventional copper-plated through holes.

Double-sided silver-paste filled-hole board: second example

Second separately photographed silver-paste construction

Send the exact hole map, connectivity netlist and expected current. Ask for the qualified fill/cure process and continuity test for this revision.

Choose the actual board family before asking for price.

The following four titles explicitly identify single-sided constructions. Their applications help route an enquiry; they do not supply safety, automotive or functional qualifications.

Flame-retardant single-sided controller PCB

Single-sided controller board; catalogue example 2

Give the material grade, flammability requirement, outline and test netlist. The flame-retardant title is not a model-specific UL classification.

Select this board route →

Flame-retardant single-sided power PCB

Single-sided power-board construction

Put operating voltage, creepage/clearance and thermal conditions on the design brief. No safety voltage, copper weight or power rating is established by the product title.

Select this board route →

Flame-retardant single-sided set-top-box PCB

Single-sided set-top-box application; catalogue example 2

Specify component holes, board thickness, soldering conditions and panel depanelisation. Ask for the approved material and incoming acceptance criteria.

Select this board route →

Single-sided PCB for automotive parts

Single-sided automotive-parts application

Identify the part function, environment and required qualification plan. Automotive use in a catalogue does not establish IATF certification or vehicle-program approval.

Select this board route →

LED backlight PCB panel

LED backlight application; corresponding original panel

Define the finished strip outline, panel breakaway and thermal path. This photograph supplies no laminate grade, thermal conductivity or metal-core specification.

Select this board route →

LED light-source PCB panel

LED light-source application; separate original panel

Provide the LED footprint, copper distribution and attachment method. Specify whether the order is bare boards or populated modules; the catalogue image is not an assembly commitment.

Select this board route →

Match the inspection record to the failure you need to prevent.

Artwork and dimensions

The workshop gallery labels photo exposure, CNC drilling and two-dimensional measurement. Request the controlling artwork revision, finished dimensions, hole tolerances and inspection sampling. No numerical positioning or finished-hole limit is disclosed by these photographs.

Continuity and appearance

Separate automatic electrical testing from AVI appearance inspection. Ask which netlist is used, how filled vias and contact regions are evaluated, and which results accompany your production lot.

Curing and thermal exposure

Carbon printing, infrared thermal curing and a thermal-shock experiment are shown. Agree ink cure, soldering exposure and acceptance limits for your order. The thermal-shock photograph is not a published test profile or a passed reliability result.

Read the company name, board type and date together.

Published UL, ISO and RoHS copies: inspect the actual scope

UL E357589 · historical Product iQ extract

The manufacturer-hosted copy names YANGZHOU JUYUAN ELECTRONICS TECHNOLOGY CO LTD at Yuesheng Road. It is last updated 2 July 2019. The first group is explicitly single-layer printed wiring boards, flammability-only recognition: JY-1/JY-1A HB and JY-2/JY-3 V-0. A separate single-layer group lists JY-4 and JY-5 with their own conductor and thermal conditions.

JY-4 shows 0.1 mm conductor width and edge entries, 17 μm conductor thickness, solder exposure 288°C/10 seconds and operating temperature 130°C. JY-5 separately lists 35 μm and 260°C/10 seconds. These are the historical recognition-type table entries, not a general minimum trace/space claim for every pictured product. Current issuer status and the actual ordered type still need confirmation.

ISO 9001 · published copy has expired

CQC copy 00122Q35013R2S/3200 names the legal entity and covers production of printed circuit boards. Issue date is 7 July 2022; expiry is 22 May 2025. An earlier copy expired in 2022. Neither copy establishes a current renewed certificate; request the renewal and applicable site scope.

RoHS · a submitted sample, not all orders

CTI report A2220513460101002C, dated 18 November 2022, identifies submitted single-board PCB samples and lists material codes. The displayed first page concludes conformity with the stated EU RoHS 2011/65/EU and (EU) 2015/863 requirement. It is page 1 of 7; the remaining pages and numerical results were not provided in the reviewed page.

A separate 2020 first-page report is also shown, but it directs the reader to following pages for results. For your order, obtain the complete applicable report and match the laminate, inks and finish to the actual material list and production lot.

Sources behind this profile

Individually researched 9 October 2026: original Chinese and English pages, ten paired catalogue photographs, named process images, readable historical document copies and the original Baoying land record. Numerical board geometry, materials and contact/via performance are not inferred from images. The land parcel, recognition types and submitted test samples remain distinct from current production or whole-order approval.
