JRPanel has more than 100+ advanced CNC automatic winding machines and automatic winding machines, etc.;The fab has excellent testing equipment, such
as comprehensive testing instruments, multi-channel withstand voltage testers, inductance testers, and programmable withstand voltage meters. There are
also a series of supporting equipment such as vacuum impregnation machine and infrared tunnel oven.
Minimum aperture up to 0.1mm for high-density interconnection (HDI) build-up multi-layer PCB, with electrical conduction between wirings on each layer controlled through interlayer vias. Currently laser drilling machines are extensively applied in processing of the Interlayer via-holes.
Via Fill is a special PCB manufacturing technique used to selectively and completely close via holes with epoxy. There are many instances in which a PCB designer might want to have a via filled. Some key benefits are:More reliable surface mountsIncreased assembly yieldsImproved reliability by decreasing the probability of trapped air or liquids.
Real-time monitoring of chemical quality in copper plating sinks.The aim of electroless copper is to plate a conductive layer through a hole or into a blind microvia.
Using the vacuum etching technology to make sure that both surfaces of the board are very uniform. it produces a straighter conductor profile, allowing the resulting plate to more accurately match the wiring requirements.
JRPanel has passed CQC voluntary certification, ISO9001 quality management system certification, and American UL certification. All products have
passed SGS environmental protection certification and comply with international REACH / RoHS certification
JRPanel strictly controls every step of the production, creates high-quality products, professional services, and fast delivery, let
our customers receive satisfactory products.
Incoming material inspection of frame and magnetic core, selected pure copper wire, to prevent defective products.
All raw materials have passed the double inspection of incoming materials and manufacturers, and they are checked at every level.
The overall appearance, process performance, brightness and size of the transformer meet the standard.
Full inspection of finished products before packaging (appearance inspection, finished product test, safety test).
Transformers/inductors are widely used in high-tech fields such as communications, power supplies, computer networks, digital
products, industrial control, science and education, medical treatment, aerospace, national defense, etc.
