Advanced PCB Manufacturing Company in California
Advanced PCB Manufacturing Company in CaliforniaWhen our customers order advanced PCBs from Rush PCB Inc., they buy quality that pays for itself over time. Incidentally, PCBs show little differences even when they differ in inherent quality. That’s because the critical difference lies under the board’s surface, affecting its functionality and durability, and the difference is hidden from the customer. Nevertheless, they can rest assured that we push the envelope such that they, in turn, receive products that always meet the most stringent quality standards.
For us, no order is too small or too large. Whether it is large-scale PCB manufacturing in California or a few highly specialized precision PCBs, we always offer our customers the best possible time to market, so that they can maintain their competitive advantage. We offer our affordable PCB assembly in California at sustainable, low total costs because of our higher competence, proven delivery accuracy, and superior product quality.

Listed below are our advanced capabilities for quick-turn PCBs:
| Items | Manufacturing Capabilities | Remarks |
| Number of Layers | 1-10 layers | For orders above 10 layers, please contact our sales rep. |
| Material | FR-4, Aluminum | For Rigid, Rigid-flex, Flex, Metal-based (Aluminum etc.), Halogen-free, HDI, High Tg, etc., please contact our sales rep. |
| Maximum PCB Size | 500 x 1100 mm (min 5 x 6 mm) |
Any sizes beyond this dimension, please contact our sales rep. |
| Board Size Tolerance (Outline) | ±0.2 mm / ±0.5 mm | ±0.2 mm for CNC routing, and ±0.5mm for V-scoring. |
| Board Thickness | 0.2 to 2.4 mm, with 0.2 mm increment. | If your board exceeds these, please contact us. |
| Tolerance of Board Thickness (t ≥ 1.0mm) |
±10 % | “+ Tolerance” typically occurs due to PCB processes like electroless copper plating, solder mask, and other types of surface finish. |
| Tolerance of Board Thickness (t < 1.0mm) |
±0.1 mm | “+ Tolerance” typically occurs due to PCB processes like electroless copper plating, solder mask, and other types of surface finish. |
| Min Trace | 0.1 mm / 4 mil | Min trace we can fabricate is 4 mils (0.1 mm). We strongly suggest designing traces above 6 mils (0.15 mm) to lower costs. |
| Min Spacing | 0.1 mm / 4 mil | The min spacing we can fabricate is 4 mils (0.1 mm). We strongly suggest to design spacing above 6 mils (0.15 mm) to lower costs. |
| Outer Layer Copper Thickness | 1 oz / 2 oz / 3 oz (35 μm / 70 μm / 105 μm) |
Also known as copper weight. 35 μm = 1 oz, 70 μm = 2 oz, 105 μm = 3 oz. Contact us if you need copper weight greater than 3 oz. |
| Inner Layer Copper Thickness | 1 oz / 1.5 oz (35 μm / 50 μm) |
For 4 and 6 layers (Multi-layer laminated structure), the inner copper weight is as per the customer’s request. Please contact us if your required copper weight is greater than 1.5 oz. |
| Drill Sizes (CNC) | 0.2-6.3 mm | Min drill size is 0.2mm, max drill is 6.3mm. Any holes greater than 6.3mm or smaller than 0.3mm will attract extra charges. |
| Min Width of Annular Ring | 0.15 mm (6 mil) | For pads with vias in the middle, Min width for Annular Ring is 0.15 mm (6 mil). |
| Finished Hole Diameter (CNC) | 0.2 mm-6.2 mm | The finished hole diameter will be smaller than the size of the drill bit because of copper plating in the hole barrel. |
| Finished Hole Size Tolerance(CNC) | ±0.08 mm | For example, if the drill size is 0.6 mm, the finished hole diameters ranging from 0.52 mm to 0.68 mm are acceptable. |
| Solder Mask | LPI | Liquid Photo-Imageable is the most popular. We use thermosetting Ink in inexpensive paper-based boards. |
| Legend Minimum Character Width | 0.15 mm | Characters of less than 0.15 mm wide are too narrow to be identifiable. |
| Legend Minimum Character Height | 0.8 mm | Characters of less than 0.8 mm high are too small to be recognizable. |
| Legend, ratio of Character Width to Height | 1:5 | This is the most suitable ratio for PCB silkscreen legends processing |
| Minimum Dia. of Plated Half Holes | 0.6 mm | Design all Half-Holes to be larger than 0.6 mm. This ensures better connection from board to board. |
| Surface Finishes | HASL with lead, HASL lead-free, OSP, Immersion gold | The most popular three types of PCB surface finish. Please contact us for other finishes. |
| Solder Mask | Yellow, Green, Red, Blue, Black, White | No extra charge for Green, Red, Yellow, and Blue solder mask |
| Silkscreen | Black, White, None | No extra charge for silkscreen. |
| Panelization | Tab-routing, perforation holes (Stamp Holes), and V-scoring | Leave a minimum clearance of 1.6 mm between boards for break-routing. For V-score panelization, set the space between boards to be zero. |
| Others | Fly Probe Testing (Free) and A.O.I. testing (free), ISO 9001:2015, IATF 16949, UL Certificate | No extra charge. |

FAQs
What are some of the most common PCB materials?
While the most common material for PCBs is FR4, a glass-reinforced epoxy, there are other materials also. These include metal cores, polyimide for flexible boards, and ceramics like alumina. Other important materials include prepregs, solder masks, and copper foils.
How do you fabricate multilayer PCBs?
We interleave prepreg layers and laminated substrates for making multilayered boards. For this, we image copper layers, etch them, and stack them up. Then we laminate them under heat and pressure. This process binds the layers into a single board. We create plated vias to electrically connect between layers.
Do you use wet etching or dry etching? What is the difference?
We use both processes depending on requirements. In wet etching, we use liquid chemicals to remove unwanted copper. In dry etching, we sputter away the unwanted copper. While wet etching is faster and cheaper, it leaves behind chemical waste. Dry etching is eco-friendly, and more precise, but more expensive.
What steps do you use for SMT assembly?
For SMT assembly, we start with solder paste printing, then place components using robots, and finally, reflow solder the assembly. In this entire process, we take care of process control parameters like paste deposition and thermal profiling.
How do you ensure PCB quality and reliability?
We extensively implement quality control steps like inspection and testing. For this we use optical and X-ray inspection to verify solder joints and components placement. For continuity and board function we use flying probe and ICT testing.
