Sorted By Characteristics
Double Sided PCB
Double sided pcbs, common in both production and prototype circuits, allow a higher density in components and make layering of tracks an easier process. Compared to multilayer pcbs, double layer pcbs do not need lamination, but need plating in order to reach through hole function.
The quick development of electronics has high requirement to printed circuit board, which single sided or double sided printed circuit board cannot reach, thus, multilayer pcbs were designed. Printed circuit board with four or more layer is called multilayer pcbs or multi-layer printed circuit board.
Flexible Printed Circuit Board is a printed circuit made of a flexible insulating substrate, with the advantages that rigid printed circuit board do not have. Rigid-flex PCBs combine the advantages of rigid and flexible printed circuit boards and can take great function of several rigid boards interconnected with cables or connectors.
Blind & Buried Via PCB
Blind holes start on an outer layer but terminate on an inner layer. Buried Vias exist only between inner layers but do not begin or terminate on an outer layer. Blind & Buried vias can be divided into two kinds, mechanical and laser. Blind and buried vias help to reach PCB density by allowing features and lines to be designed above.
Impedance control PCB
The most common example of a controlled impedance component is the downlead (or feeder) connecting a receiving aerial to a wireless or television set. For bare board pcbs, we can do single ended impedance control and differential impedance control pcbs, and the best tolerance we can do now is ±5%.
Gold Finger PCB
Gold Fingeris agold-platedterminal of a card-edge connector, usually, fingers are done by flash gold (hard gold) and the gold thickness is requested to be from 3u to 50u because fingers are mainly used for pluging for many times. We have great advantage in gold finger pcbs production, and now, the thicknest gold we can do is 50u.
Lead Free HASL PCB
Lead free HASL PCBs are cheapest compared to Immersion tin silver gold pcbs, except OSP pcbs. However, OSP surface finish has disadvantage of short storage time and get oxidized when open in the air. Lead free hasl advatanges: Excellent wettability, good shelf-file, excellent solder joints, low cost, excellent reflow cycles, excellent surface oxidation and so on.
Immersion Tin PCB
Immersion Tin is the lead-free alternative to the Hot Air Leveling(Hasl) process on pcbs. On PCB surface and the bore holes, the thickness of Tin is between 0.7 μm and 1um. The tin layer protects untreated copper from oxidation; it is a perfect foundation for soldering applications, as well as for plug contacts during the production of PCB.
Immersion Gold PCB
Immersion Gold, also called ENIG, has been growing as one of the best finishing methods for printed circuit boards. ENIG is a costlier finish, but offers the best characteristics for pcbs. Immersion gold chemistries offer many strengths like excellent surface planarity coplanarity, excellent wettability, long shelf-life and surface oxidation.
Immersion Silver PCB
Immersion Silver Plating is a surface plating technology used for Printed Circuit Boards,it is deposited directly on the copper surface by a chemical displacement reaction and is available in the industry all co-deposit and organic anti tarnish with the immersion silver. This reaction is fast and does not require the relatively high temperatures of ENIG.
Carbon Conductive Ink PCB
Especially conductive inks' high conductivity and its excellent abrasion resistance provide excellent long term reliability results. Excellent definition due to optimized Rheology, Excellent adhesive strength and mechanical stability, Resistant during HASL, High chemical resistance, Protecting during plating processes by peelable soldermask.
Flash Gold PCB
Flash gold was one of most famous surface finish on PCB in the past, it is replaced by immersion Gold (also called ENIG or soft gold) because of appreciation of gold. The gold thickness by flash good will be thicker than immersion gold, and now, flash gold is only used in special places like gold fingers.
We provide customers with quality, reliability and a single point of support.

Sorted by Material
High TG PCB
High TG materials have better mechanical strength, dimension stability, adhesiveness, moisture absorption, thermal decomposition, and thermal expansion than normal TG pcbs.
Aluminium Based PCB
Aluminum base have excellent flame retardant, high mechanical strength, dimensional stability etc. Especially it has very good heat sink, electromagnetic shielding and solder float.
Iron Based PCB
The iron-based PCB use material for the base is from special steel, silicon steel and ect in stand of FR4 or CEM1 and can dissipate heat away from critical board components and to less crucial areas such as metallic core or the metal heatsink backing.
Cu Based PCB
Plate surface smooth, dimensional stability, high strength, easy processing. because of small thermal resistance, cu based PCB are widely used in industrial power equipment, automotive ignition, regulator, speakers...
As famous and expensive base material in the world, Rogers have its obvious and remarkable advantages like high frequency,high reliability and stability, as well as the dielectric constant evenly distributed (which is the fatal defects of other pcb materials).
As another kind of high frequency material, Teflon are widely used in wireless networks, wireless communications and satellite communications, in particular the popularity of 3G networks exacerbate the market demand for the product on the HF PCB.
Arlon's materials are used in a variety of applications, which have typically require laminates with specialized electrical, thermal, mechanical, or other performance characteristic that exceed those of traditional standard FR-4 materials.
Halogen Free PCB
“Halogen-free” means the product material does not contain any compounds derived from these elements. Halogen free pcb have a characteristics of safety, Higher Application Temperature, Environmental Initiatives Fire Damage Prevention and so on.
