Sierra Standard Product for your PCB manufacturing and assembly

The Sierra Standard Product is our new online quoting and ordering platform for PCB manufacturing and assembly. Quote and order your assembled circuit board within 5 minutes. Receive your products within 10 or 15 days. Our circuit boards are proudly fabricated and assembled in Silicon Valley.

The Sierra Standard Product offers real-time stock visibility and seamless integration with suppliers to ensure transparent pricing. You can receive an online quote for PCB manufacturing, components, and assembly, all made in America, in less than 5 minutes.

  • PCB fabrication
    All PCBs are made with US materials and are built to IPC-A-6012 Class 2 in our Silicon Valley facilities.
  • Component procurement
    Components are procured from authorized distributors, checked for counterfeit, and electrically tested.
  • Assembly
    0201 component placement through our Pick-and-Place machines with AOI and X-ray.

At Sierra Circuits, our engineers and turnkey PCB build teams are always accessible and responsive throughout the entire process, from the initial quote to production and shipping. We take pride in offering top-notch American-made PCB solutions.

Sierra Standard Product Fabrication & Assembly Capabilities

Board Type Only rigid boards. Standard Product service provides both fabrication and full assembly of your boards (including component procurement).
Board Shape We expect boards to be generally rectangular in shape. Notches, cutouts and slots are allowed (some restrictions shown below).
Board Spec Boards will be built to IPC-6012 Class 2 Spec. However, in this online offer, we do not provide any microsection certificates or IPC coupons to customers.
Fabrication of ITAR / EAR Controlled Designated Jobs? No
RoHS Available? Yes, your board can be RoHS if you choose RoHS-compliant surface finish (ENIG). You have an option to not have any RoHS markings on your board if you so choose.
Layers Allowed 2 layers, 4 layers, 6 layers, and 8 layers.
Laminations Single lamination double-sided or multi-layer boards only. In this online offer, we do not provide boards that need multiple laminations or have HDI features.
Blind Vias No
Buried Vias No
High-Density Interconnect (HDI) No. In this online offer we only provide single lamination PCBs with through-hole vias.
Non-Plated Holes Yes
Data for PCBs For PCBs: We prefer RS-274X extended Gerber format or ODB++.
Data for Assembly For assembly: You will need to upload your BOM (excel format) online for quoting. In the final package, we will need the assembly drawing and XY data.We prefer ODB++ data for your orders that require assembly.
Turntimes 5 days for PCB fabrication, or 10 days for fully assembled boards.
Cut-Off Time 5:00 PM. Day 0 begins when validation is done or the final consigned components are received, whichever is later.
Order Quantities For most designs, quantity 5 & 10 assembled PCBs available. Some limitations apply based on the number of panels to be produced and the turntime expected.
Maximum Board Size Must fit a 15" x 9" box.
Minimum PCB Dimensions 1" x 1"
Material Lead-free FR4 (RoHS compliant)
Thickness & Thickness Tolerance 0.062" with thickness tolerance of +/- 10%.
Arrays Arrayed designs are not allowed. Your PCB design must have just a single image of a single board. (Our engineers will array it as needed for Sierra assembly and finally ship you fully-assembled individual boards.)
Minimum Trace / Space 4 mils
Standard Copper Overplate Surface pattern: Nominal 1 oz/sq foot. (0.0013" to 0.002") (33 microns to 51 microns)
Outer Layers Copper (Finished) 1 oz.
Inner Layers Copper You can choose between 0.5 or 1 oz.
Maximum Number of Holes Per Board 80 holes / square inch
Minimum Annular Ring Width 0.006"
Controlled Dielectric In this online service, you cannot specify controlled dielectric, but we offer +/-10% controlled impedance (see below).
Controlled Impedance ? In this “standard product” we only offer impedances of 50 Ohm Single Ended, 90 Ohm Differential, and 100 Ohm Differential. To get these impedances, the trace width/spacing on your design on specific layers must adhere to our impedance table provided. For each of the 2 layer, 4 layer, 6 layer, and 8 layer product we have provided impedance tables that you must refer to and match your design to the trace widths required and we will manufacture your board to meet those specific impedance requirements.
Multiple Parts in one design To keep our online service low-priced and hassle-free, we keep it simple. We do not allow different PCB designs and multiple BOMs to be combined in one order. Our system can only accept design files for a single circuit board with a single BOM. We cannot merge BOMs, de-duplicate multiple BOMs, etc.
Soldermask Green.
Legend / Silkscreen White.
Notches, Cutouts and Slots Up to 10 plated slots allowed per board. Up to 10 non-plated slots allowed per board. Up to 10 cutouts allowed per board. Up to 10 notches allowed per board. (If any of the above allowances are exceeded in your design, we can still process it for a minimum $100 extra lot charge on your order. We will get your approval before doing so.) Minimum inside radius (for any notch, cutout or slot) = 20 mil (0.02"). Minimum width (of any notch, cutout or slot) = 40 mil (0.04").
Logo Vendor markings include Company Logo, UL marking, Flammability, etc. Such vendor markings will be put in Bottom Silkscreen.
IPC coupons & Microsection reports Not provided in this online offering. Only available in custom ordered products.
Electrical Testing 100% net-list testing on every board.
Shipping Options FedEx / UPS, Will Call. You can use your own FedEx / UPS account number. International shipments allowed. All duties / customs are the responsibility of the customer.
Payment Terms Credit card (PO allowed for select customers who have set up credit terms). Payment link convenience: If your purchasing department typically puts in credit card number, you can still place an order and our system will email a payment link to that person. Order will start when payment information is received.
Assembly Class Specs IPC-A-610-Class2
Assembly of ITAR Designated Jobs? No.
Assembly on Both Sides Yes.
Minimum Passive Component Size 0201 (inches)
BGA Minimum Pitch 0.5 mm. BGAs cannot have more than one ball size nor more than one pitch.
Minimum Pitch of Other Components 0.4 mm
Maximum Number of Through-Hole Components 20 per board
Minimum Component Pad Size Minimum 8 mils x 8 mils or 8-mil diameter
Assembly Restrictions These features are not allowed: Wire-bonding, conformal coating, underfills, staking, POP assembly, wire/cable assembly. Rework like cutting traces, wire jumpers. Assembly of PEM nuts, turrets terminals, rivets, and press-fit connectors.
Other Restrictions No First Article Reports will be provided
