Gold fingers impedance control PCB

Basic Info

Model No.: Srorm-0013

Product Description

What are gold fingers?Gold Fingers are the gold plated narrow connectors found on the edge of printed circuit boards to enable connections between multiple boards. They are made from flesh gold, the hardest form of gold available and work for a long time with superior conductivity. The thickness of gold fingers usually ranges from 3 to 50 microns.

Gold is chosen for these fingers as it has the highest corrosion resistance and electrical conductivity after Copper and Silver. Sometimes, Gold is combined with Cobalt and Nickel to increase the resistance of the fingers for wear and tear. PCBs are connected/disconnected from each other multiple times. So these connection points (fingers) need to be able to handle some wear and tear.
We can offer impedance control PCB with Gold fingers also.If you want to get this design more quickly,Quick turn impedance control will be meet your request.Pls send Gerber files to us if you have any 4 layer impedance control PCB.Storm Circuit is a professional PCB and PCBA manufacturer in china. We have been manufacturing PCB and offer assembly services with component supplying for client around the world over 10 years.

Top 10 Reasons Why You Should Buy PCBs and PCBAs From Storm Circuit
1.TOP Quality-
-It must be the first important key.We always put quality as the first.In PCB industrial,we have over 99% equipments in house. Drilling,Plating,Pressing,AOI (Auto-optical Inspection),Testing,etc.That is why we can guarantee our quality.
2.Shipping On Time even Early.

Our Standard lead time for 1-2 layer is 5 working days,Multi-layer 6-8 working days.What is standard? see details. And our Express Service offer 1-2 days for double sided boards,3 days for multilayer boards.

3.High Mix boards.

Whatever you need normal FR4,high TG ,Aluminum board,RF board with low Er,PTFE(Teflon),heavy copper.large board,high tech board with blind/burried vias.impedence control boards.we can offer such products in quick turn as we have many different material in stock.

4.Technical Support.Free DFM,

free file review.Many customers (especially for some designers) are not good at manufacturing process,even they can not generate correct gerber file from their EDA.With much experience in PCB industrial,here are some design tips for you.7*24 online support except our Chinese New Year.

5.StormProto Service.
what is stormproto ? see here.You want to cut prototypes cost,that is our stormproto value.With this service,you can save at least 50% cost.
6.Reasonable Price.

7.Fast Response,Fast Shipping.

Each enquiry can be replied in 2 hours.2-3 days from us to your door.see shipment.

8.NO MOQ.

We do not have any minimum quantity requirements,even -one board for PCB fabrication and assemble.

9.One Stop Service.

We not only produce PCB ,but also PCBA and cable assemble .A bare PCB is not what you want,you may need stencil to screen,components to load and cable to connect. Now,you can throw all to us and wait your final product on your desk.

10.Large in-house stock of parts.

We have many components stock in house,that is you will save much time and cost on your total project.Especially for any resistors,capacitors,relays,ICs.
