Abstract

The invention belongs to the technical field of coating equipment and particularly discloses an EMI shielding film magnetic control winding coating machine. The EMI shielding film magnetic control winding coating machine comprises a vacuum room body, a door body and a target room. A winding roller system is arranged in the vacuum room body. A plane magnetic control target system is arranged in the target room. A low-temperature coating roller is partially placed in the target room. The plane magnetic control target system comprises multiple target work sections, multiple pairs of plane magnetic control targets are arranged in at least one target work section, every two adjacent target work sections are separated through a separating plate, and all the plane magnetic control targets are arranged around the low-temperature coating roller in a manner of being away from the surface of the low-temperature coating roller by the equal distance. The coating machine can be used for achieving one-time film walking, all the targets work at the same time, the overall deposition rate can be greatly increased, the requirement for one-time coating of multiple layers of films of multiple materials can be met, in addition, a relatively low temperature can be reached, heat is effectively discharged, and it is ensured that a coated flexible base material cannot be deformed when heated.

Description

technical field

[0001] The invention belongs to the technical field of high-vacuum continuous winding coating equipment, and in particular relates to a magnetron winding coating machine for EMI shielding films. Background technique

[0002] EMI is electromagnetic interference, which is electromagnetic waves emitted by electronic devices during operation, which interferes with nearby electronic components or devices. Usually, in order to ensure the normal operation of the device, these external influencing factors must be isolated.

[0003] Eliminate electromagnetic interference, most commonly using electromagnetic shielding. At present, there are many methods of electromagnetic shielding, which can be as follows: metal braided sleeve, conductive paint or film, tin foil, copper paper or metal box. The above-mentioned shielding methods have a common feature, that is, a continuous conductive layer that passes electromagnetic waves through The ground wire leads to the ground, w...

Examples

Embodiment 1

[0028] Such as figure 1 As shown, a kind of EMI shielding film magnetron roll-to-roll coater of the present invention comprises vacuum chamber body 1, door body 2 and target chamber 3, and described vacuum chamber body 1 is provided with winding roll system 4 and ion Source 10, the target chamber is provided with a planar magnetron target system, and the winding roll system 4 includes a protective film winding roll 41, an unwinding roll 42, four guide rolls 43, a low-temperature coating roll, and a protective film wound sequentially. 44 and winding roll 45, the right side of the low temperature coating roll 44 is partially placed in the target chamber 3, the planar magnetron target system includes four target working sections 5, each target working section 5 is provided with a pair of The planar magnetron target 6, the adjacent target working area 5 is separated by the partition plate 7, and each planar magnetron target 6 is arranged around the low-temperature coating roll 44 ...

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, the difference is that: there are four target working areas 5, and the two target operating areas 5 placed in the middle are air extraction compartments 5 without planar magnetron targets 6 installed. ', there are two planar magnetron targets 6 in the target working area 5 placed on both sides, so that the different gases in the front and back areas can be effectively blocked to achieve the effect of not affecting each other.
