PCB Board ESUN have produced are mainly used in the Industrial Control, Medical Treatment, Automobile area,LED lighting,communication,aviation and so field on.All PCBs are ISO9001, ROHS, UL certificate and meet the international IPC standard.

PCBA for fiber optic transceivers and switch electronics. Demands are typically signal integrity and thermal management.

The flexible part of the rigid flex PCB usually features a multilayer built with padded through holes securing the interconnectivity between layers. Rigid flex PCB has grown from merely using the flexible substrate as a replacement for wire harnesses, to having actual subcircuits built on the flexible area itself.

The double-sided PCB (double-layer/double-sided printed circuit board/breadboard) is more complicated than single sided PCB. The circuits on both sides are connected through the middle Various types of double-sided PCB are on the market, such as double sided copper clad PCB, high Tg thick copper foil PCB, high-frequency PCB, and hybrid dielectric base high-frequency double-sided PCB. Double-sided PCBs are widely used in high-tech industries like telecommunications, power supply, computers, industrial control, digital products, scientific and educational equipment, medical equipment, automobiles, aerospace defense.

There are conductive patterns on both sides of the insulating substrate, generally using metallization holes to connect the conductive patterns on both sides cause both sides have conductive patterns, such PCBs can be used through metal holes to wrap the wiring to the other side and interleaved with each other, so it can be used on more complex circuits.

Multilayer circuit boards have at least three conductive layers, two of which are on the outer surface, and the remaining layer is synthesized within the insulating board. The electrical connection between them is usually achieved through plated through holes in the cross section of the circuit board.

Aluminum PCB consists of a dielectric metal base with a bonded copper circuit layer to create superior heat transfer to help cool components while eliminating problems associated with managing fragile ceramics. E-SUN works to be the best aluminum PCB manufacturer when it comes to exceeding all customer expectations.

Technology highlights：Multilayer boards with a higher connection pad density than standard boards, with finer lines/spaces, smaller via holes and capture pads allowing microvias to only penetrate select layers and also be placed in surface pads.

Rigid-flex PCB is derived by bonding two rigid outer on flexible PCB. The circuit of the rigid layer and flexible layer are connected by metalized hole.

No brief introduction

HDI boards has the are 6 different types of HDI boards, through vias from surface to surface, with buried vias and through vias, two or more HDI layer with through vias, passive substrate with no electrical connection, coreless construction using layer pairs and alternate constructions of coreless constructions using layer pairs.
