What is the difference between flexible PCB and just scratching the printing circuit board?
Gangrou combined with print circuit boards allows you to have the advantages of both the beauty. The rigid soft combination of PCB combines the flexibility of the flexible circuit and the durability of the rigid PCB. Flexible printing circuit boards are only flexible materials, which are usually based on polyimide or polyester. They can be single, double or multi -layer boards. The rigid soft combination of PCB also uses flexible and rigid materials. The flexible layer is sandwiched between the rigid layer. The rigid layer has conductors and plating holes to connect the flexible layer to other layers.
The flexible circuit board itself may not bear the wear of some challenging applications, but the standard rigid board is often very heavy and occupies a large amount of space. Combining rigid boards and flexible circuits can reduce weight and save space, and provide you with streamlined products that can be used for various industrial environments.
Suggestion of the layout of PCB just scratching board PCB
Gang scratching combined with PCB suppliers provides guidance in layout and bending to ensure your equipment safety. We want to provide a quick overview to help you understand the thickness and other requirements that may be needed in the design.
Calculation of circuit constructor curved radius calculation
1 layer (single -sided) flexible thickness X 6
2 layer (double -sided) flexible thickness X 12
Multi -layer flexible thickness X 24
Other design skills include:
Avoid 90曲 bend as much as possible.
Slowly turning is always safer.
The curved radius is measured from the interior of the bend.
The conductor through the corner needs to be perpendicular to the corner.
Use a curved wiring instead of a routing line.
The wiring should be vertical with the curved.
Rigidity combined material
Your specific rigid printing circuit board will be customized and produced. However, in order to let you start thinking about what you need to consider, we want to share some materials that can be used for your project with you. Our consulting services, knowledge and capabilities have made us one of the leading suppliers of just scratching printing circuit boards.
For just scratching the printing circuit board or any printing circuit board, the correct material is essential. PCB using unqualified materi
als may fail, break, fire, generate dangerous sparks, or affect your operations in a critical moment.
KKPCB uses the best material for each rigid PCB to ensure that you get the ideal results in terms of signal transmission, thermal guidance and security.
Main material
The following are some of the main materials we use to ensure the excellent quality and performance of just scratching circuit boards:
Standard FR-4 Material
Lead-free compatible FR-4 material
High -speed digital material
RF and microwave compatibility materials
Metal core (ie aluminum) material with high heat -conducting
Polyimide
Covering layer, coverage coating and flexible welding layer
DuPont, Panasonic, Shengyi, Thinflex, etc.
Trimming
PCB is usually finished after welding. Precision processing can protect copper pads from pollution, prevent corrosion and oxidation.
The choice of surface treatment depends on the composition and expected use of the circuit board. In KKPCB, we are happy to negotiate with you to determine the most suitable PCB surface processing.
We provide various types of PCB precision processing types, including:
Enig
Hard golden finger
Sinking silver
Soak
Electrolytic gold that can be combined with leadership
insulator
The insulator isolation conductive layer and component on the PCB to control the temperature and prevent unnecessary electrical conductivity. They are combined with flexible substrates and coverage materials to form various thickness and shapes. Circuit boards require appropriate insulators to supplement the conductor -the wrong insulation experience leads to poor PCB performance and eventually leads to failure.
Some common insulators include:
FR-4
Polyimide
Polyester fiber
Polycuric acid ethylene glycol (PEN)
Polyzhenylene glycol (PET)
Welding layer
Flexible welding layer
A sensing cover film (PIC)
Silk net printing electrical medium
Commander
In PCB, copper is the most commonly used conductor. Copper is an ideal choice for PCB, because it is a high -electrical material, so it can easily transmit signals without losing electrical energy. Copper has high ductility and ductility, so it is easy to shape into thin PCB layers, thin lines and other components.
The copper type commonly used in PCB includes the following:
Sinking copper
Voltice delay degradation (RA) copper (mainly used for rigidity combination application)
The bottom copper in our PCB is usually thin copper foil and copper plating. We provide the following number of finished board copper per square foot, of which the thickness per ounce is at least 0.0007 to 0.0014 inches per ounce:
1 ounce
1.5 ounces
2.0 ounce
More than 3.0 ounces
