1. Bill Of Materials (BOM)
We can accept your BOM in a number of formats but we recommend that you use WOW Circuit’s Formated BOM when building your BOM. Please be sure to set the 'Type' field to the correct value and use DNP (do not populate) for any components we will not be placing. Your BOM should include:
Quantity of each part type
Reference designator
Part number (Digi-Key, Mouser, Newark part numbers are okay)
Part description
Package description (QFN32, SOIC, 0805, etc. package is very helpful but not required).
Type (SMT, Thru-Hole, Fine-pitch, BGA, etc.).
2. Gerber’s
Please include all Gerber files. At a minimum we need top and bottom silkscreen, copper and the solder paste layers.
3. Centroid
It should include component locations, rotations and reference designators.
Our Assembly Process
There are a number of tasks that we must complete after you place your turn-key PCB assembly order. These tasks include:
Once you placed your Kitted PCB Assembly order, there are a number of tasks that we must complete after you place your order. These tasks include:
1. Verify for the required files and your order details.
2. Order the SMT paste stencil and verify with raw pcb when received.
3. Prior to receipt of materials we will Program our machines from the BOM and Centroid file you supply.
4. Upon receipt of Materials are we will verify for correct qty’s and verify for correct parts per current BOM before your job is run.
5. If the files are received before 10:00 am, Run Clock will start if all materials are in before that time, the assembly clock starts that day. If after 10:00 am, the clock starts the next business day.
6. Unless Assembly job is a small run manual assembly order, SMT stencil and stencil printer are used to mechanically apply the paste.
7. At WOW Circuits, we use Mycronic Pick and Place Assembly equipment to place the SMT components.
8. Depending upon complexity of assembly we use either 1 7 zone or 10 zone reflow oven to reflow solder onto the SMT components.
9. All BGA and Leadless components with belly pads are X-rayed to verify placement accuracy and to detect any solder bridges.
10. Thru-hole parts are inserted by hand. They may also be selective solder depending on the board layout.
11. AOI Inspection may be used to perform Inspection of assembly before Final Inspection
12. A final quality check is performed per IPC-A-610 Class II or III per assembly request.
13. All residual materials will be either sent back to customer or held at WOW Circuits if requested for future assembly.
