Description
Technical field
The utility model is related to stiffening plate technical fields, and in particular to a kind of new type compound stiffening plate.
Background technology
Stiffening plate is called Stiffeners, reinforcing plate, reinforcing plate, and support plate protects strong plate, reinforcing rib.Stiffening plate is mainly used
It is building, petroleum pipeline, machine construction equipment, electronic product etc..It is widely used, mends in FPC flexible circuit boards in electronic product
Strong plate mainly solves the suppleness of flexible PCB, improves the intensity of plugging position, facilitates the overall package of product.Stiffening plate
Mainly there are stainless steel stiffening plate, aluminium foil stiffening plate, polyester stiffening plate, polyimides stiffening plate, glass fiber-reinforced plate, polytetrafluoro
Ethylene stiffening plate, makrolon stiffening plate.Stainless steel is unlikely to deform, and has higher intensity, can play conductive and induction work
With, for example, the golden finger back side reinforcement steel disc, for increasing the hardness and thickness of golden finger, be convenient for plug, the thickness of FPC steel reinforcement
Degree is generally 0.1mm, 0.12mm, 0.15mm, 0.18mm, 0.2mm, 0.25mm, 0.3mm etc..FPC steel reinforcement materials have stainless steel
304,301 etc..FPC steel reinforcement use scopes are in mobile phone, videophone, laptop computer, aerospace, medical instrument, number
The FPC of the compression modules such as code camera, automobile instrument or the link member of LCD panel, it is most to be presently used in mobile phone camera position.
Traditional FPC stiffening plates are typically all to use to open grinding tool punch forming, but Sheet Metal Forming Technology is relatively rough, and tolerance is big, and precision
Not high, burr is difficult to clean out, and is easy to form wiring board the influence of short circuit or open circuit, what most steel disc reinforcement used
It is the technique making of chemical etching, etch process solves the requirement to high-accuracy parts in industrial production, this advanced work
The FPC stiffening plates that skill is manufactured, minimum-value aperture can reach 0.1mm, and hole wall is vertical, without any burr；Flatness is kept
It is the way of domestic contrast prevalence in 0.02mm hereinafter, minimal tolerance can accomplish +/- 0.01mm.Aluminium foil is usually to be used in heat dissipation

(POLYESTER) stiffening plate is commonly used in the position of not soldering part.Polyimides (POLYIMIDE) stiffening plate has higher
Temperature tolerance is commonly used on the FPC plates of welding spare part.Glass fiber-reinforced plate is called FR-4 (GLASS EPOXY) or FR4,
It is divided into high temperature resistant FR4, fire-retardant FR4, the FR4 of resistance to ablation, high-strength F R4, high toughening FR4, antistatic FR4 plates.Hot pressing stiffening plate,
Pressure sensitive stiffening plate, thermal sensitivity stiffening plate.Hot pressing stiffening plate：The thermmohardening glue of reinforced rubber sheet is melted using high temperature, and
Using appropriate pressure or vacuumizing makes reinforced rubber sheet be fitted tightly on product.The hot pressing glue that FPC is used also is hot-setting adhesive.Heat
Solid glue is solid-state at general temperature, without viscosity, but when temperature rise to a certain extent after, can be transformed into very strong sticky
Semi-cured state, FPC and stiffening plate are clung at this time（Common practices is after reinforcement is directed at bonding position, to scald 1 with electric iron
~ 2s plays One-Point Location.After carry out hot pressing, i.e. high temperature and pressure, allow whole face glue thoroughly to flow bonding, basic at this time is difficult separation
）.Using baking, further glue is done and is cured.Want lamination reinforcement plate that can generally mark this process, Er Qiehui on flow list
FPC drawings are issued in lamination reinforcement station, drawing includes FPC external forms, reinforcement external form, the two bonding position.Pressure sensitive stiffening plate：
Without heating, product is pressed by cold press, and reinforcement can be sticked on product.Existing stiffening plate meets to enhance its intensity
Use demand can only be continuously increased the number of plies and thickness of stiffening plate so that cost greatly improves, and size is continuously increased, Jin Erxu
To increase installation space for it.
