What is PCB Polimide?

A PCB polyimide Is a flexible print circuit board that uses polyimide as a dielectric substrate, provides extraordinary flexibility for flexible, folding, or turning repeatedly without mechanical damage. This polymer offers extraordinary thermal stability, handling temperatures up to 400 ° C, low dielectric constants near 3.5, and high tensile strength, making it suitable for electronics that require dynamic movements or complicated three -dimensional three -dimensional packaging.

Generally applied in nerve implants and devices that can be used, this PCB allows reliable electricity connections in a limited space while maintaining performance under pressure. Fabrication involves compatible techniques with microelectronics, supporting mass production for high density interconnection in all medical and consumer applications.

How thick is the PCB Polymide?

Core material thickness

• Polyimide base film ‘:: Usually “”12.5 îief to 100 îief (0,0005â € “0.004 inches) â € œwith “25 îief (0.001 inch) “and” 50 îief (0.002 inches) “become industrial standard.

Total Stackup thickness

• Single -layered flexible PCB ‘: “50” 125 “ (0.002 € “0.005 inches)” when combined with copper foil (9 “18”).
• â € œMulti-layer designs’:: The range of â € œup to 0.3 mm (0.012 inches) “for 4” “6 layers Configuration uses adhesive bonds.

Factor affecting

• Copper foilâ € œ:: Ultra-thin “9” 18 îief “The electrodeposition copper reduces large amounts.
• “ Bonding Films adds “10” 25 î¼m ‘per layer; The adhesive lamination reduces the total thickness to “30 îiefm”.
• â € œFuffeners’:: Localized PI or Steel Assistance (“0.1 “0.3 mm”) increase the connector zone.

What is the thermal conductivity of PCB flexible polymide?

What are the pros and cons of the Polimide circuit board?

Pro (profit) “

• High cable density and miniaturization ‘:: Activate compact design for applications that are limited in space such as mobile devices or items that can be worn.
• Light and thin profileâ € œ:: Reducing the weight and thickness of electronic products as a whole, ideal for portable electronics.
• Very good flexibility and durability. Can withstand millions of dynamic bends without wire damage, supporting complex 3D assembly.
• Flexibility in the spatial layout ‘:: Allows scaling and arbitrary movements in a three-dimensional space for integrated component connections.
• Extensive application “:: Suitable for high fields of reliability such as aerospace, military, and digital cameras because of the strong isolation nature.

Cons (loss) “

• High initial costâ € œ:: The design process, stomach, and photography are expensive due to special manufacturing requirements.
• Limited use for general applications’:: Usually justified only for specific needs, not cost effective for standard PCB.
• Maintenance Challenges’:: Repair and re -work, such as solder, requires trained personnel to avoid damage.

What is the application of PCB Flexible Polymide?

PCB application flexible polymide

How is PCB polyimide produced?

The process of making a flexible polymide PCB

1. Material preparation

• Basic film: Polyimide (PI) film (12.5â € “50 μm) was chosen for thermal stability (TG> 250 ° C).
• Adhesive layer: Epoxy/acrylic adhesive is applied to the film PI for copper bonds.

2. Cladding copper

• Lamination: The adhesive -plated PI film that is laminated with electrolytic copper foil (1/3â € “2 ounces) in 180 €” 200 ° C.
• Temporary transportation: Aluminum/steel carriers are installed for Ultra-thin FPC to prevent warping.

3. Circuit pattern

• Dry film application: Dry films are laminated photosensitive to copper.
• Exposure & Development: UV lamps explain the circuit pattern; Areas that are not exposed are swept away.
• Etching: Eta ferrik chloride/alkaline removes unprotected copper (width of the line/distance ‰ ¥ 25 µm).

4. Coverlay application

• Pi Covery: The second film with a laminated adhesive on the circuit for protection.
• Laser ablation: Co “laser drill the precision hole (via/pad opening).

5. Coating & Final Surface

• Enig Plating: Nickel gold/electric soaking applied to bearings for solderability.
• Bonding Bonds: The FR4/PI is attached to the connector zone through thermal bonds.

6. Testing & Inspection

• AOI: Automatic optical inspection for defects (open/short circuits).
• Electricity Testing: Flying test/bed nails verify continuity/impedance.

7. Cutting & Formation

• Laser cutting: The formation of precision from the outline of FPC.
• Bending Test: Validation of flexibility (1,000+ bend cycles at 180 °).

8. Final cleaning & drying

• Ultrasonic cleaning: Eliminating residual particles from ETSA/coating.
• Burning: FPC is dried in an 80 “100 ° C oven to eliminate moisture.

9. Packaging

• Anti-static protection: FPC is placed in an anti-static bag with a dryer package.
• Bearing: Foam inserts or trays formed by vacuum used to prevent movement.
• Labeling: Barcode/QR Code Label includes product IDs, batch numbers, and Rohs compliance.

10. Check the final quality

• Visual inspection: Confirm there is no scratches, folds, or contamination.
• Electricity re -testing: Sample testing for critical parameters (for example, impedance).
