It sounds like a brilliant, low-cost plan. The Next Big Thing gets built and delivered to your customers for presumably the lowest cost. That&#;s a win, right?

Maybe. Maybe not.
Having your project spread out amongst many vendors may seem great on paper, but it can also create a lot of unknowns. You&#;ll want to consider the full cost of your mechanical assembly, including potential hiccups before fully committing to that piecemeal build.
You know that time is your most important commodity and, among other variables, this is the most likely hidden cost in your piecemeal build.
The extra time when the boards and the wires don&#;t line up right and have to be redone. Time lost when the project needs adjustments and you have to work through all the previous vendors. More lag time when the shipping company doesn&#;t have the right packaging to protect your project.
You and The Next Big Thing deserve a better way that can cut down on these losses and potentially even save you money from the start.
What you need is a start-to-finish box build with one electronic contract manufacturer (ECM) that can reduce your shipping timelines, streamline your assembly process, and reduce your costs.
How can this be, you ask? How can a single source ECM compete with the cost savings you saw in your plan with multiple vendors?
The secret is in limiting too many hands and too many transitions. Single source ECMs like Levison Enterprises, promote cost savings by limiting the number of vendors and thus, limiting the number of &#;cooks in the kitchen.&#;
Why would too many &#;cooks&#; be a problem?
The Next Big Thing is complex, right? You&#;ve got detailed plans and have thought through the entire assembly process. At the same time, you know that it&#;s likely that design changes may need to be made as assembly gets started, possibly even after The Next Big Thing is in the manufacturing stage.
When those changes happen and your needs evolve, partnering with a single source ECM will allow you to make changes with one vendor instead of having to contact multiple places. With one vendor, you eliminate the potentially disastrous costs of miscommunication, and worse, lack of accountability somewhere in your mix of vendors.
Cost is a compelling decision point and the costs of &#;what-ifs&#; are difficult to determine. The following is intended to help you get the full picture of your costs and consider the potential losses in common &#;what-ifs&#; when it comes to electronic box builds.

Always try to keep your completed board size to a minimum. The bigger a board, the higher your material cost. However, this also works the other way around. If you make your board excessively small, a manufacturer will need very precise equipment to produce it. So it&#;s a balancing act for you to navigate between size and complexity.
Skimping on materials, usually costs in the long run. Use standard, quality materials in your layer stack.
If at all possible, design your board in the standard square and rectangular shapes. Unusual shapes, increase manufacturing costs significantly. Try to avoid internal cutouts to your Printed Circuit Board unless absolutely needed.
As spacing between copper feature like pads and tracks decreases, the more manufacturing costs increase. The more packed into a smaller package, the more precise the manufacturing processes will be required. Many fab houses have a standard set of spacing requirements, which is somewhere around 8-10 mils minimum spacing between pads, tracks and track widths. Check with your manufacturer to see their specific spacing requirements. And save yourself from some added worry about adding design rules in your Printed Circuit Board (PCB) Design software for these spacing requirements so you don&#;t need to think about it while you design.
The smaller the holes and annular rings, the higher you&#;re the manufacturing costs. Again, it comes down to smaller spacing needing more precise machinery.
There are three types of vias
Blind and buried vias should only be used when absolutely needed - for high density and high frequency PCBs.
Before adding additional layers for more routing space, power planes, or performance, think again. The difference between a four layer board and a two layer board is double. Only use as many layers as needed, even if it means making the board size a little larger.
PCBs are manufactured on large production panels with other like PCBs. One can save money by using the largest panel size available from your manufacturer. In assembly maximizing the number of PCBs on a panel means that rapid-fire pick and place machine can operate much more efficiently, avoiding additional machine set-up time.
There&#;s a reason why the electronics industry uses a standardized set of sizes and components &#; it makes everyone&#;s job easier and more efficient. It also adds some potential for automation in all of those high-tech pieces of manufacturing equipment. So to extra costs, stick with industry standard parts.
Using surface mount components reduces the amount of holes that need to be drilled on a board. This also reduces the number of processes required to soldered components onto your board.
If you do decide to go with a mixed-component technology with both surface mount and through-hole parts, then prepare for some added costs. This type of setup will require multiple passes through the soldering oven and some manual hand assembly. If unavoidable, then try to keep all surface mount parts on one side of the board.
