Excepting OEM PCB, i.e. Telecommunication, PC Add-On Card, IT Application, Network Device, Multi Layers FR-4 product, we have some outstanding products as follows:

1. Carbon Built on PCB: Apply for Thick Film Technology to make the PCB with buried resistors or touch pad function. It is to reduce cost and increase productivity without any function lessened. We have achieved the filed in memory module PCB and touch pad.
It is easy to imaging a staggering number of resistors in the finished board. We use an unusual technology to embed carbon resistors in our multi layers boards instead of trying to populate all of resistors with external components; it saves space and, hence, increase the speed of system and short the production time consumed.
RAMBUS RIMM PCB: It is a new challenge to make 8 layers PCB with strict impedance control as 28 Ohm 10%, and 4/4 mil trace. As a normal Multi layers PCB, the registration among layers only allows 6 mil of tolerance. This is a breakthrough in the PCB industry. With over a year of efforts, we started the mass production starting 2000.

PCB layout considerations for non-isolated switching power supplies
Henry J. Zhang, Applications Engineering Manager, Power Products, Linear Technology Corp. - July 20, 2012


Save Follow
The best news when you power up a prototype supply board for the very first time is when it not only works, but also runs quiet and cool. Unfortunately, this does not always happen.
A common problem of switching power supplies is "unstable" switching waveforms. Sometimes, waveform jittering is so pronounced that audible noise can be heard from the magnetic components. If the problem is related to the printed circuit board (PCB) layout, identifying the cause can be difficult. This is why proper PCB layout at the early stage of a switching supply design is very critical. Its importance cannot be overstated.
The power supply designer is the person who best understands the technical details and functional requirements of the supply within the final product. He or she should work closely with the PCB layout designer on the critical supply layout from the beginning.Power Management DesignLine

PCB layout techniques to maximize power module performance
Don Rhodes and Marc Davis-Marsh, National Semiconductor Corp.
8/22/2010 9:55 PM EDT
A new class of easy-to-use power modules offers an alternative to complex power designs and the printed circuit board (PCB) layout issues typically related to DC-DC converters. Nonetheless, there is still some engineering to be done when designing with and laying out these power modules, which integrate an inductor and a monolithic synchronous regulator within one power package.

Pads (also called leg guards) are protective equipment used by batters in the sports of cricket and baseball, and by goaltenders in hockey, bandy and lacrosse. They serve to protect the legs from impact by a hard ball or puck at high speed which could otherwise cause injuries to the lower leg. In cricket, pads fall into two types, batting pads and…

I am going to make a double sided PCB and was wary about Track widths re power disipation.
Based on the motor running full there is a possiblity to run at 50Amps.
This is a fair amount over a PCB.

Has anyone ever designed a board using this dsort of current.
Supply Voltage is 12Vdc.

The datasheet gives a foot print guide but I really feel the trach or surface area is to be around 50mm.
Correct me if I'm mistaken.

The MOSFET is suited to high current with heatsinking.

As mentioned any feedback based on PCB copper layout would be greatly appreciated.
This article describes the best PCB layout methods, practices and techniques to maximize the SIMPLE SWITCHER power module’s performance. It also discuses relevant thermal issues, and its lessons apply to other power-supply designs, as well.

A good layout design optimizes supply efficiency, alleviates thermal stress, and most importantly, minimizes the noise and interactions among traces and components. To achieve these, it is important for the designer to understand the current conduction paths and signal flows in the switching power supply. The following discussion presents design considerations for a proper layout design for non-isolated switching power supplies. Matrox G400/450 Bug when doing part name displays on NT

Location of the Power Supply in System Board
For the embedded DC/DC supply on a large system board, the supply output should be located close to the load devices in order to minimize the interconnection impedance and the conduction voltage drop across the PCB traces to achieve best voltage regulation, load transient response and system efficiency. If forced-air cooling is available, the supply should also be located close to the cooling fan or have good air flow to limit the thermal stress.

2. Thin PCB: Less than 16 mil thickness in 4 or 6 layers FR-4 production is another challenge for our production capability. From raw material control, producing inner conductor to lamination, we have to develop many tools to handle the interior materials that are thin as paper. Those materials are mostly used in PC CARDs and some MEMORY CARD, such as the MEMORY STICK, COMPACT FLASH etc. We had produced over 200,000 pieces monthly for Flash Card or Flash Card Reader device in past. The performance is resulting from our outstanding board thickness control and thin PCB process.

3. CSP // BGA PCB: Because the chipset supports high frequency, many requires BGA package, i.e. AGP card, DDR 400 etc. We understand that it is not only for surface flatness, but also for filling VIA holes. Those kinds of PCB are increasing and we expect the quantity will be over 10% of our production in coming years.
