Our design services - PCB Layout, Electronic Projects Engineering, High Quality, Low costs & Fast Service, backed up by great support.

Design Capability:
The electronic design is called a schematic or circuit diagram. It is constructed in CAD format.At China-low-cost-PCB we use Protel, OrCAD, PADs,CAM350,Genisis... We have an experienced design house/ bureau be family with both military & commercial projects, can do many product Research and Development work(R&D).We have over 80 active accounts with major component manufacturers & distributors (most with Internet access & next day delivery). If the part you require is out there, we'll find it for you.

The Printed Circuit Board (PCB) Layout
The connections on the PCB should be identical to the circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation between the circuit and the layout.
PCB layout can be performed manually (using CAD) or in combination with an Autorouter. The best results are usually still achieved using atleast some manual routing - simply because the design engineer has a far better judgement of how to arrange circuitry. Surprisingly, many autorouted boards are often completely illogical in their track routing - the program has optimised the connections, and sacrificed any small amount of order that may have been put in place by manual routing. Generally autorouted boards are slightly harder for a technician to repair or debug, for this reason. Historically, PCBs used to be laid out by drawing or using stick on paper shapes on mylar film, - that really WAS manual routing!

The CAD PCB layout consists of several layers, for illustration purposes the holes, outline and component identification layers can be combined into one diagram. When we produce PCBs for clients, we use actual size checkplots during the design process. A PCB will usually have mounting holes and may possibly have cutouts, by cutting an actual size checkplot and placing it in the enclosure, you can see how it will be positioned in relation to other parts. We can also place components up against the pad markings as a quick double check of sizing.

The secret to creativity is knowing how to hide your sources. -- Albert Einstein
We put a bit of effort into the PCB design - it is somewhere where quality of design can make a difference. These days most circuit boards are automatically assembled and tested - but you will still have people working on your circuit boards, and having a quality design can make all the difference between a product that is pleasant to work on and one that they will hate. Machine test points, for ATE (Automated Test Equipment) bed of nails testing, just need to be pads or lands. Some test points, however, are not really intended for ATE but rather for engineering test or modification - we put labelled test points on for these, as illustrated.
We put a complete silkscreen identification overlay on most of our boards, and the quality of this is another way we can make a better product. The silkscreen contains important information that assists people to service and install the product. Aside from functionality (which is rather obvious) the overlay is the chief distinguishing feature between a purpose-built product, such as we deliver, and a general-purpose product such as you might buy from a company like Rabbit. We would label terminals as: "+12v red" "-pwr black" "solenoid+" "solenoid-" whereas competitors may often just give you: "A1 A2 A3 A4". They don't have much of a choice - they have no idea what you will attach to the terminals.

For dense surface mount boards, we often need to leave off component values, and sometimes need to omit the component designators. The silkscreen is the primary method for labelling connectors, replaceable parts, orientation, and even installation notes (for instance "Remove J2 while replacing battery - observe battery polarity")

The PCB layout also needs to take account of EMI and ESD compliance and we have a seperate page on some techniques that we use to get our PCBs to comply. We have a tutorial on designing PCBs - it steps through the CAD process from schematic to layout. We also support the Autotrax/Easytrax CAD package by providing Updated video drivers. If you are intending to design PCBs yourself, we would recommend this very good manual on PCB layout. OPTIMUM DESIGN ASSOCIATES
