PCB Design Services And Solutions

By Jeannie Chapman

PCB design services involve specialized activities aimed at creating an optimum printed circuit board layout using CAD software and other specialized PCB design tools. There are different kinds of PCBs and the process for each one may vary a bit. Regardless of the type of board or layout, though, it's always going to be roughly the same multi-stage designing process that begins with schematic capture.

At this point, it would be appropriate to note that the client is usually required to provide the designer with information about at least three basic aspects. One is the aforementioned schematic, although it may also be provided by the client as a netlist file. The netlist is simply a file that contains all the connectivity information for the design, along with descriptions of components used.

The BOM or bill of materials is another key requirement which contains a listing of all the components to be used and their footprints. Some designers offer to do the component footprint capture process too. All this and the board outline together provide the designer with everything needed for getting started with the design process.

Starting from the netlist/schematic, the process is taken further using techniques including library development, signal integrity and EMI checks, stress analysis, thermal simulation, etc. The series of intermediate steps ends with the creation of the gerber file. This format is the preferred one used by the electronics industry to transfer finished PCB images that are ready to be used in the manufacturing stage.

Designers must be able to work on complex solutions involving everything from digital and analog to RF circuits and mixed PCBs. The board can be designed as per specifications as a single or double sided board, or a multi-layered one. The size is also likely to vary, and so will other factors such as component quantities and pin densities.

There's also the question of deciding on the characteristics of the board. This refers to the method used to mount components and create the traces for the circuit. Surface-mount technology is the most popular technique used now for mounting components.

Using this surface-mount technique, the end caps are directly soldered now on the same side of the board. This new method has almost completely replaced the earlier through-hole boards. In these older boards, leads were inserted from one side of the board and soldered onto traces on the other side.

Apart from the schematic capture and subsequent board designing steps, the designer may also be called upon to evaluate existing designs, components and footprint captures. Sometimes they're also involved in prototype procurement, and may be asked to do availability checks and collect pricing information against the BOM.

As a matter of fact, PCB design services continue to be required even after the product is delivered. Customers frequently need to make changes, and reorders bring a lot more business. Reverse engineering is another service that needs a highly skilled designer. In this case, the designer is given the gerber file and must come up with the schematic or netlist, which the client can then use for making wide-ranging changes.

Which Models Of Portable Wireless Speakers Produce The Smallest Amount Of Noise?

By Linda Cullmann

It is easy to be confused by the terminology that cordless loudspeaker makers employ to depict the performance of their products. I am going to explain the meaning of one regularly used spec: "signal-to-noise ratio" in order to help you make an informed decision whilst getting a brand new a pair of cordless speakers.

After you have narrowed down your search by looking at some fundamental criteria, including the amount of output wattage, the dimensions of the loudspeakers plus the cost, you are going to still have quite a few products to choose from. Now it is time to look at some of the technical specs in more detail. The signal-to-noise ratio is a fairly important specification and describes how much noise or hiss the wireless speaker makes.

Comparing the noise level of several sets of cordless speakers can be accomplished fairly simply. Just collect a couple of versions which you want to compare and short circuit the transmitter audio inputs. Afterward put the cordless loudspeaker volume to maximum and verify the amount of static by listening to the speaker. You are going to hear some amount of hissing and/or hum coming from the speaker. This noise is produced by the cordless speaker itself. Make certain that the volume of each couple of wireless speakers is set to the same amount. Otherwise you will not be able to objectively compare the amount of noise between different models. The general rule is: the smaller the level of hiss which you hear the higher the noise performance.

While taking a look at the cordless speaker spec sheet, you want to look for a set of wireless loudspeaker with a large signal-to-noise ratio figure which suggests that the cordless loudspeakers output a small amount of noise. Noise is generated due to several reasons. One factor is that modern wireless loudspeakers all employ components such as transistors as well as resistors. Those components are going to produce some amount of hiss. Typically the components which are situated at the input stage of the built-in power amplifier will contribute most to the overall noise. Consequently producers usually will pick low-noise elements whilst designing the wireless loudspeaker amp input stage.

A different cause of static is the cordless music broadcast itself. Normally products which make use of FM style broadcast at 900 MHz are going to have a rather high level of noise. FM transmitters are quite prone to cordless interference which is why newer products usually utilize digital music broadcast. This style of music transmission offers higher signal-to-noise ratio than analog type transmitters. The level of static is dependent on the resolution of the analog-to-digital converters in addition to the quality of other components.

The majority of of recent wireless speaker use amplifiers which are based on a digital switching topology. These amplifiers are called "class-D" or "class-T" amps. Switching amps incorporate a power stage which is always switched at a frequency of approximately 400 kHz. This switching frequency is also noise that is part of the amplified signal. However, latest cordless loudspeakerspecifications generally only consider the noise between 20 Hz and 20 kHz.

Producers measure the signal-to-noise ratio by means of setting the built-in amplifier such that the full output swing can be achieved and by feeding a test signal to the transmitter which is normally 60 dB below the full scale of the loudspeaker amplifier. Next the noise-floor energy is calculated in the frequency range between 20 Hz and 20 kHz and compared with the full scale signal energy.

Often you will find the expression "dBA" or "a-weighted" in your wireless loudspeaker parameter sheet. A weighting is a method of showing the noise floor in a more subjective way. This technique tries to examine in how far the cordless loudspeaker noise is perceived by human hearing which is most sensitive to signals at frequencies at 1 kHz. As a result an A-weighting filter will amplify the noise floor for frequencies that are easily perceived and suppress the noise floor at frequencies which are barely heard. Most cordless loudspeaker will show a higher A-weighted signal-to-noise ratio than the un-weighted ratio.

Some Types Of Power Sources Designed For Wireless Surround Sound Products

By Mike Heller

You will find a few options available designed for adding rear home cinema loudspeakers such as directly wiring the loudspeakers to your Home theater receiver or making use of a wireless surround sound kit to eradicate the speaker cable mess. Then, let me look at the power sources which supply these wireless products with energy plus demonstrate a few of the most crucial requirements which those power sources must meet.

Cordless surround sound systems include a transmitter unit that connects to a home entertainment receiver and one or several cordless receiver modules. While those sets do away with the dreadful speaker cord, they are not really cordless since both the transmitter and also receiver have to be powered. Several cordless receiver devices possess an integrated power supply and attach to a mains outlet by means of a cord whilst others come with an exterior AC adapter.

Wireless receivers that have an external ac adapter do not have to integrate a power source. Therefore these may be manufactured significantly smaller sized. The exterior wallwart normally is quite small too and often plugs directly into a mains wall socket. An additional kind of wallwart is quite similar to the kind made use of by notebooks for the reason that it hooks up to a mains wall socket by using a short power cord. Having a separate wallwart wouldn't seem very useful. Having said that, from a maker's point of view you'll find several advantages. Almost all nations have got unique mains outlets and voltages and as a result having a separate power source provides a larger amount of versatility for making the system for every particular country. Also, separate wallwarts are less expensive to have accredited for safety and in addition are less costly to exchange in case they become faulty compared to changing the complete receiver. Wireless surround amps with integrated power source are easier to set up considering that they directly plug into a mains outlet. However, they are generally a bit more bulky.

The power supply of cordless loudspeaker systems should satisfy numerous prerequisites. The very first requirement is usually that the power source needs to be accredited to satisfy the local safety rules. Safety rules are created to safeguard an end user from being wounded when utilizing the equipment and covers ares like galvanic insulating material in between the output and input. On top of that, the power source should never overheat in the course of typical function and also have adequate protection just in case of an overload. Power sources that have passed safety testing typically carry a UL or CE symbol. When the power supply is integrated into the cordless receiver then the receiver carries this symbol.

The power source should provide plenty of power for the RF receiver and also power amplifier component. The RF receiver component decodes the wireless music transmission. The current prerequisite of the power source mainly varies according to the power amplifier RMS wattage specification plus efficiency. The lower the amp efficiency the greater the current that the power source has got to supply. To be able to meet the power specification, the power source must provide adequate current to the amp to continually output the specified wattage no less than 10 minutes. The power source peak current rating can be important as regular music signals have got brief bursts of high energy. A further prerequisite would be that the power source voltage should really be pretty constant plus have as little ripple and noise as possible. A few power amps are able to make up for power supply ripple and noise. Several high-end music gear utilizes linear power sources irrespective of their weight plus dimensions because of the very good noise behavior. Many power sources are switch-mode power supplies. The supply voltages of the RF receive and power amplifier section are usually different. For that reason lots of power supplies provide several supply voltages. Last but not least, the power source must have ample overload and over-temperature safeguards to keep everything safe in the event of a fault with the power amplifier.
