It frequently does not sound right to put money into expensive manufacturing equipment in the event that you only want to spin some prototypes and instead outsource your PCB meeting and prototype manufacturing to your dependable seller. I will give some tips about what to watch out for when searching for a contract manufacturer.
Many contract manufacturers will pcb manufacturers in usa supply an immediate quote mechanism in their site for manufacture of circuit boards and assembly of prototypes. This will save time when you compare different vendors. Make sure that the quote system lets you enter all the details, such as plank material, thickness, copper thickness, milling etc. so you are able to get an exact quote with no surprises later on.
Usually the cost per board will decrease as volume increases. That is because of the fairly substantial setup cost of circuit board manufacturing and component assembly. Some sellers can use a platform where they join boards from several customers. This way the setup cost is going to be distributed amongst several customers. When you produce something, you obviously do not desire to have to manufacture a large number of boards straight away as you refine your own design.
1 restriction with small-quantity prototypes though is that the choice of materials and material thicknesses is likely to likely be limited. If you are using a particular cloth then odds are there will not be no customers using the very same material. In addition, leadtime plays a big role in determining cost. A more lead time makes it possible for the manufacturer more freedom in slotting your production. This is typically represented in lower costs which you may see in the quotation section. Clearly if you’re in a rush and want to be moved to the surface of the pile you will want to invest more money.
Be certain your contract manufacturer may encourage the document format for fabrication that you provide. The most common arrangement for PCB manufacture may be that the Gerber format however a few vendors will also accept board records from common PCB software products. Some suppliers also offer in house PCB style. Even if you plan your board yourself, deciding on a seller with design services may prove invaluable in case there’s a problem with your files. In cases like this your seller can make quick changes which will avoid expensive delays.
When sub contracting PCB assembly, ensure that your vendor can assemble most of the package types that your board uses. Some vendors can’t construct certain type of IC packages such as BGA, chip-scale bundles or very small component types. If in doubt be sure to contact your vendor ahead of time.
Some contract manufacturers will probably hold an inventory of regular SMT and through-hole components. You will save time if you’re able to pull from your seller’s inventory as opposed to purchasing each component your self. Be sure that you specify which components you would like to consign your self if you upload your own bill of stuff.
Most vendors will also offer manufacture of their SMT stencil which is required for PCB assembly. Be sure to order the stencil right out when ordering the circuit boards themselves to prevent accidents.
To ensure your circuit boards will probably work, make certain that your seller is quality certified and offers the tests and board inspection methods that are required. Please be aware, nevertheless, that one tests, such as for example ICT testing requires additional cost and time to prepare proper evaluation fixtures.
