4 layer LED PCB board
Basic Info
Model No.: Storm-0402
Product Description
The main purpose of using an aluminum PCB board is that it has good heat dissipation. Due to the high heat generation of high-power LEDs, most aluminum PCB boards are used in the production of LED lighting fixtures. FR-4 glass fiber circuit board is a traditional electronic product circuit board. Because of its good insulation, corrosion resistance, compression resistance, multilayer PCB board and Other characteristics, it is widely used.
The product quality of LED aluminum PCB is mainly based on the material model, hardness, surface and thickness of the aluminum material. It is also necessary to choose a suitable model size according to the heat output of the product. FR-4 glass fiber circuit board is a relatively mature product. Most of the LED display screens use FR-4 glass fiber circuit board.

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
Our price is NOT cheapest but is the most reasonable cost.You trust us,then we can offer you our best products and service.
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.
