Face is pasted onto on polyimides high temperature gummed tape, carries out ionized physical vapor deposition method sputter, makes corium RF-type fingerprint recognition
In device main body, in addition to first side, other faces obtain the coat of metal；
S004, complete first time sputter after, corium RF-type Fingerprint Identification Unit main body is put into UV stove, removes polyimides
Viscosity on high temperature gummed tape, to strip down corium RF-type Fingerprint Identification Unit main body from polyimides high temperature gummed tape；
S005, complete to peel off for the first time after, then corium RF-type Fingerprint Identification Unit main body is overturn, will be with first side phase
To second side be pasted onto on a new polyimides high temperature gummed tape, carry out second sputter, make in first side obtain
The coat of metal, simultaneously because the diffuse-reflectance of sputter, after sputter twice, the 3rd side of corium RF-type Fingerprint Identification Unit main body
The coat of metal that face and the 4th side similarly obtain integrity covers；
S006, complete second sputter after, corium RF-type Fingerprint Identification Unit main body is put into UV stove, removes second and gather
Peel off again after viscosity on acid imide high temperature gummed tape；
S007, complete second stripping after, remove protecting film, obtain finished product, realize in corium RF-type Fingerprint Identification Unit
Upper sputter package metals shell.
The present invention is in view of the known defect of traditional Automatic FingerprintVerification device packed by metal casing technique and inconvenience
And the one kind proposing is conducive to greatly reducing volume and carries high-quality corium RF-type Fingerprint Identification Unit metal shell sputter
Packaging technology scheme, realizes RF-type Fingerprint Identification Unit and can be applied in the removable and unconstrained any field of size；This
Technique be capable of at high speed, in high precision, the possibility of free of contamination technical advantage and extensive industrialization, meet industry and utilize,
Be conducive to improving production efficiency and quality, there is good economic benefit and social benefit.
