When designing a new item, or revising an existing one, designing and finding a model of the Printed Circuit Board (PCB) is most often a difficult and costly job. When we examine the reason why that is so, we will find methods to really make the process easy.
As with any product that is designed PCB prototype to a specification, a new printed circuit board comes with some up front costs which would be the same no matter how large, or small that the manufacturing volume is. To design a board, or update an existing one, can have an engineering price. There’ll also be a cost to producing a brand new solder mask for the new board. Remember if you change one component or you also completely redesign the board, any change in a covered solder mask, then will take a new one to be made.
It’s a frequent misconception which a tiny change at the PCB, should have a little charge to understand that shift. As you see, a shift can be a change about the price of printing the board. Additionally, it doesn’t follow for the engineering. It is often the case that somebody has a product designed years ago by one engineer they want marginally modified by yet another engineer. The new scientist will need to examine the present design to see how best to execute the desirable change.
This is sometimes bothersome into the company paying for the bill since they may feel more happy to pay for the price of a brand new PCB whenever they only desire to alter their existing PCB.
The way to get around this is to plan ahead whenever you’re designing PCB from scratch and utilize a firm which may help do this.
Let’s take the case of a PCB that in addition to power and a power on lighting, may have two inputs and two outputs. It is possibly, if improbable, that additional features are needed for its next iteration of the product, let’s mention 4 inputs and 3 outputs and a display. The specifics of this desirable iteration are never to the forefront . however, it’s logical that the following iteration would gain using that, sometime in the near future (this can be even years later).
Keep in mind, there is a fixed cost into the solder mask and also the engineering time. The added cost of technology the future desired attributes is minimal in comparison with cost of designing from scratch. Just since there’s circuitry on your PCB does not mean you have to populate it when you have planks made. You are able to in character make a board that includes two revisions.
While it is true you’ll still need to produce alteration to the software on your microcontroller, this will probably be easier and cheaper than revising the entire board.
This is going to be particularly true when you keep good notes in the plank and also a fantastic replica of the software with notes on where you wish to modify it.
Once you’re seeking to have PCB designed and assembled, look for a firm that’ll help you sort out those issues. Use their expertise to find out what’s reasonable to plan for and what is not. In case the firm you are working with does not need to aid you with this; try to find yet another one which really does.
