Double-sided PCBs(Double-sided Printed Circuit Boards)are one step up above single-sided printed circuit boardin their complexity.
Double Sided PCBs require plated through holes between top and bottom pads to provide better anchoring for soldered components. Today the double sided printed circuit board technology remains the workhorse of the assembly industry. There are near limitless applications for old and new designs. Fine line surface mount, ultra high copper build, high and low temperature, Solder coated, Silver, and Gold finishes are just a few examples of double sided board applications.

General specification for Flexible PCB
Because of the advantages, such as: cost, space, and weight savings, flexible and Rigid-Flex-circuit board shave for some projects, they are used ever more frequently.
Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. Multi FCB can produce your flexible circuit boards with the highest quality, either as prototypes or in series.

Demand for heavy copper PCB in Electric automotive, computer, industrial controls, and military is growing very fast. More than 80% of the existing printed wiring board manufacturing is limited or not capable of producing reliable heavy copper printed circuit boards.
The driver behind the demand of heavy copper core PCBs is ever increasing power requirements in power products and the elimination of complex wired buss configurations. Hitechpcb has been associated with heavy copper pcb plating since 2000 and we have good quality on it.
Heavy copper PCB - General specification
In PCB industry for thick Copper core PCB or Heavy copper PCB people generally use the name to identify a printed circuit board with copper thickness more than 3 Oz in inner or outer layers and extreme heavy copper PCB refers to more than 15 Oz printed wiring board.
Thick copper board technology offers the possibility to implement complex switches in limited space in combination with circuitry for high current levels. Multi-layer PCB has reliable processes to produce copper layer thicknesses up to 20 Oz .
Heavy copper PCB normally used for high power rectifiers, Computer, military, Electric vehicle charging, power grid switching system, etc.
Aluminum based PCB, also named Aluminium PCB, metal clad(MCPCB) PCB, insulated metal substrate(IMS or IMPCB) PCB, thermally conductive PCBs, etc. It is generally including single layer, double layer and multi layer.
Operating theory:
The power device surface mounting on circuit layer, it is ideally suited for the mounting of high power light emitting diodes (LEDs) easily dissipating the heat generated by power devices.
Aluminum based PCB used:
Aluminum base PCB used:
1. Audio devices: input, output amplifiers, balanced amplifiers, audio amplifier, preamplifier, power amplifier.etc.
2. Power Supply: Switching Regulator,DC / AC converter,SW regulator.
3. Telecommunications electronic equipment: high-frequency electric amplifiers ,Filtering appliance ,Transmitter circuit,etc.
4. Office automation equipment: Electric motor, drives.etc
5. Automotive: Electronic regulator, Ignition, Power Controllers.etc
6. Computer: CPU board ,Floppy drive ,Power Device.etc
7. Power Modules:Converter, solid-state relay ,Power Rectifier bridges,etc
8. Lamps Lighting: with the promotion of energy-saving lamps, Aluminum base PCB , used on LED lights ,begin large-scale application.
Rigid flex PCB circuit are a hybrid construction flex circuit consisting of rigid and flexible substrates which are laminated together into a single structure. Each layer of rigid-flex circuit are electrically interconnected by plated through holes (PTH), which is different from a flexible circuit with FR4/PI stiffener on top or bottom of flex circuit only by the means of preventive or thermal sensitive adhesive only, no PTH.
Printed Circuit Board Manufacturer
Rigid-flex board enjoy the advantage of both rigid FR4 PCB and flexible circuits. In rigid area, components will be soldered on, and whole board can be bendable at the flexible circuit area, so that to save space of assembly, make whole product into a small size but with tight trace designing.
Also people don't need to solder the FPC on PCB, or connect FPC on PCB via connector, furthermore, that plated through hole interconnection is more stable, firm than soldering or connector. So more and more rigid flex board circuit has been widely used in both military and civil area.
