When designing a new solution, or revising an existing one, designing and securing a prototype of this Printed Circuit Board (PCB) is most often a difficult and expensive job. If we examine why this is so, we’ll discover ways to make the process easy.
In the same way as any product that’s built to your specification, a brand new printed circuit board comes with some in advance costs which are exactly the exact same regardless how large, or small the manufacturing volume is. To design a new board, or revise a current one, may get an engineering price. There will still be a charge to building a new solder mask to the new board. Remember whether you change just one component or you also completely redesign the board, any change in a covered solder mask, will take a fresh one to be made.
It’s a common misconception which a small change at the pcb manufacturing usa , ought to have a small charge to realize that change. Since you view, a change is a change regarding the price of printing the board. It also doesn’t follow for your own technology. It is often the situation that some body has an item designed years ago by one engineer they want marginally modified by yet another engineer. The new engineer will have to reassess the current design to see how to execute the desirable change.
This can be frustrating to the company paying the bill as they can feel more happy to cover nearly the fee of a new PCB whenever they just want to alter their existing PCB.
The way around this is to plan ahead when you’re designing PCB from scratch and work with a business which will help do this.
Let us take the example of a PCB that in addition to power and a power on light, could have 2 inputs and two outputs. It’s possibly, if improbable, that additional features are needed for the upcoming iteration of this product, let us state 4 inputs and 3 outputs and a display. The particulars of the desired iteration are never to the forefront but it’s plausible that the following iteration would benefit out of this, sometime in the foreseeable future (this really is years after ).
Keep in mind, there’s a fixed cost into the solder mask and the technology time. The added cost of technology the near future desirable features is negligible in comparison with the cost of designing from scratch. Just since there’s circuitry in your PCB doesn’t mean that you need to populate it when you yourself have boards made. You can in character make a board that includes two revisions.
While it is true you’ll still need to make modification to the software on your micro controller, this will probably soon be easier and cheaper than simply entering the entire board.
This is going to be especially true if you keep good notes on the plank and also a great replica of the software with notes to where you need to modify it.
Whenever you are trying to get PCB designed and assembled, start looking for a firm that’ll help you sort out these issues. Use their expertise to check out what’s reasonable to shop for and what is not. If the firm you are working with does not want to help you with this; then try to find yet another person that really does.
