It all started

when someone ( a fledgling pcb designer ) discovered that an acid would disolve copper and an acid would not disolve ink. Place the ink on a copper clad sheet of fiber glass in a pattern. Imagine silkscreening lines or patterns on the copper. Imagine acid eating the copper away from the ink pattern. This process is called etching. The result is a pcb design of several lines. a pcb assembly or pcb layout, of copper on the fiber glass now called a pcb board. These lines are made of conductive material (copper or some other conductive metal) and the material upon which the copper rests or adheres upon cannot carry electricity - it is an insulator. Any electricity applied to the copper line will follow the copper to the destination. We now have a printed circuit board design based upon a schematic capture of the money making idea.

Lines can be designed

so holes can be drilled or punched through the copper line, Now components can be placed through these throughholes and soldered. The result eventually becomes an electronic device - a printed circuit board layout or design or PCB.

So what do you get?

The electrically conductive pattern portion of the PCB assembly allows electrical current to flow to the various electronic components populating the circuit board. These components perform various functions such as resisting current flow (resistors), amplifying (amplifiers) or changing the direction of current flow (diodes and/or transistors).

PCB's

(printed circuit boards) are used in almost every and any technical electronic device. These devices range from rockets, to trains, to television sets, to computers. They are everywhere in one fashion or another - even in the computer monitor that you are using to view this message.

Now to the practical side

what we are quite capable of doing for you. We can provide up to a 12 multi-layer pcb layout design for your product concept and are looking into up to 18 layers of design and production. We can design your circuit allowing surface mount soldering of your components, and/or design your PCB for through hole mounting of your components be they small transformers, resistors, capacitors, or other combinations.

We Are TURN-KEY !

Overseas production

We can oversee a complete manufacturing of your device produced by our overseas contract manufacturer.

We utilize companies described below for

For the complete assembled product we utilized Whitways as one of our offshore manufacturers. They apply highest level of manufacturer quality specification to your product. Their High speed pick and place machine is capable to place 100K components per hours. After completion of the PCB assembly an automated visual inspection is performed. This is followed by a full functional test. The quality and of the solder paste and accuracy of the stencil is checked by an optical system.

For your product components we utilized companies described below:

For PCB manufacturing we use
Greenteke Inc.
They are top quality and most reliable board supplier. They utilize fling probe to test the prototype board against the netlist from the Gerber file. Four heads drilling and routing machine can do up to five layers of the boards at the same time.

Ningbo SYL Precision Metals Co.,Ltd is the mould manufacturer.

The first step of the mold making they create a master copper model of the plastic part for electroforming process . They utilized high quality steel for their injection plastic mould. They prepare a decorative logo engraving and final surface finish as the last step of the mould making. It takes up to 6 weeks to get the finished injection plastic part .
