Prototyping / Batch service for 1 Layer , 2 Layer , through hole 4 Layer , 6 Layer PCB 

Professional skill : we checked your gerber file and raise question ( if there is ) before production 
Kind customer service : we suggest the best way such as panelize your PCB for fabrication to lower your cost  
Attractive price :
A -flexible price for actual gerber size and quantity ; B -VIP price for VIP customer; C- extra-low price for standard PCB prototyping 

Gerber Rulers 

Gerber Files: If you are ordering the first time make sure that your design is comply with  following min/max limits:


Separated Sub-Boards: for seperating boards please use a slot according to following pictures. Drilling holes or other methods for seperating boards will be NOT accepted. Boards which are seperated only by silk-screen are counted as sub-boards and have to be payed extra. Junctions between V-Slots are always crossing (X). For other junctions like (T) or (L) you need to use the normal milling and not the V-Slot.


Panels: For higher quantities (depending on the used area) we will combine your PCBs automatically to a panel. If you don ot want it or want to define your own panel then contact us before ordering at sales@smiery.com .

E-Test: All PCBs are getting a 100% AOI (Automated Optical Inspection) to make sure that all tracks and pads are connected.
In addition to this the PCBs can be tested by a flying probe to make sure that all vias are connected, because this is not visible by the AOI.
1-layer PCBs don't need this tests because there are no vias.
4- and 6-layers will be tested always 100% with a flying probe.
For 2-layer PCBs we provide 100% e-test .

: We are not taking any responsibility for your Gerber files. We are using them as-they-are for producing the PCBs, so make sure that they comply with all limits and standards.

Flex & Rigid-Flex Circuits

Flex & Rigid-Flex circuits can be shaped to fit where no other design can. They are a hybrid of ordinary printed circuit boards and round wire, exhibiting benefits of each.In essence, flexible circuits give you unlimited freedom of packaging geometry while retaining the precision density and repeatability of printed circuits.As a high reliability replacement for wire 
and wire harness assemblies, flex circuits provide a significant cost savings with no reduction in performance.There are a variety of terminations for flex circuits and we can provide all of these as standard manufacturing process.  Adding connectors and other minor component assembly is a common practice when producing flex and rigid flex circuits.

Types of Flex Circuits

Each type of flex circuit offers different advantages. While some types of flex circuits can offer lower production costs, others have additional increased functionality.
We provide early design services for all your Flex and Rigid-Flex needs. From selecting the best functional configuration to choosing the proper connectors or components, we will help you with your product from early design stages to production.

Rigid-Flex Circuit Benefits

Rigid Flex circuits gives the ability to design your circuitry to fit the device, instead of building a device to fit the circuit board.
