It usually does not make sense to invest in highly-priced production equipment if you just want to spin a couple of prototypes and alternatively outsource your PCB assembly and prototype manufacturing to a trustworthy vendor. I will give some suggestions as to what to watch out for when looking for a contract manufacturer.
Quite a few contract makers will supply an instant quote mechanism on their web page for manufacture of circuit boards and assembly of prototypes. This will save you time when comparing diverse vendors. Make confident that the quote system permits you to enter all of the details, such as board material, thickness, copper thickness, milling and so forth. so that you can get an correct quote without the need of any surprises later on.
Generally the expense per board will reduce as quantity increases. This is due to the relatively higher setup cost of circuit board manufacturing and component assembly. Some vendors will use a technique where they combine boards from various customers. This way the setup price will be distributed amongst various buyers. When you manufacture a product, you obviously do not want to have to manufacture a big quantity of boards ideal away though you refine your design and style.
One particular limitation with small-quantity prototypes although is that the option of supplies and material thicknesses will be limited. If you are working with a special material then chances are there won’t be any other shoppers employing the same material. In addition, lead time plays a massive part in figuring out price. ball grid array enables the manufacturer extra freedom in slotting your production. This is commonly reflected in reduce costs which you will see in the quote section. Obviously if you are in a rush and want to be moved to the prime of the pile you will need to have to invest more income.
Make certain that your contract manufacturer will help the file format for manufacture that you give. The most prevalent format for PCB manufacture is the Gerber format but some vendors will also accept board files from frequent PCB computer software merchandise. Some suppliers also present in-home PCB style. Even if you style your board your self, picking a vendor with style services could prove useful in case there is a difficulty with your files. In this case your vendor can make quick adjustments which will stay away from costly delays.
When subcontracting PCB assembly, guarantee that your vendor can assemble all of the package kinds that your board utilizes. Some vendors can not assemble particular form of IC packages such as BGA, chip-scale packages or really compact element kinds. If in doubt be confident to get in touch with your vendor ahead of time.
Some contract suppliers will carry an inventory of standard SMT and by way of-hole elements. You will save time if you can pull from your vendor’s inventory rather than buying each element oneself. Make positive to specify which components you want to consign oneself when you upload your bill of supplies.
Most vendors will also provide manufacture of the SMT stencil which is required for PCB assembly. Be sure to order the stencil right away when ordering the circuit boards themselves to stay clear of delays.
To assure that your circuit boards will perform, be sure that your vendor is high-quality certified and offers the tests and board inspection strategies that are required. Please note, on the other hand, that specific tests, such as ICT testing calls for additional time and expense to prepare suitable test fixtures.
