Smart Cards New Technology for Producing RFID Inlays by 70Khz
Ultrasonic Wire Embedding Machine
Brief Introduction:
Ultrasonic smart card welding equipment transmitted ultrasonic
energy through welding parts to welding area, local high
temperature will happen due to high acoustic resistance between two
welding interface places. Also, no enough time dissipating out
heating energy timely because of poor plastic thermal conductivity,
heating energy gathered in welding area since could not dissipating
out timely, the two plastic contact areas will welt rapidly,
coupled with a certain pressure, it makes fusion to one unite. When
ultrasonic stop function, and keep the pressure sustain to make its
solidification molding, finally forming a strong molecular chain,
which achieve the purpose of welding. And the welding strength can
close to raw material body strength.

Benefits:
In the production of Bank card, smart card and VIP, which need to
dip tin coils and then welding.
ultrasonic welder can welding wire directly, the welding spot has
the following benefits:
1. welding spot firm, prevent to cold Weld.
2. same size welding spot, consistency.
3. welding spot small, easy to press fit package.
4. eliminating the need for pre-welded solder dip process,can hire
less one operations staff.
5. its welding is faster than iron.
6. the production process will not produce exhaust gas waste
pollution.
7. 70KHz ultrasonic unit, speed welding, low production costs.
8. Stable frequency of ultrasonic automatic planting line machine,
and could adjust frequency according to customer requirements.
Compare with etching antenna technology:
Ultra-thin IC card is made possible by ultrasonic embedding
process.It will effectively solve the problem of the failure of
etching antenna technology in the application of ultra-thin IC
card, which can reduce the scrap rate and reuse cost.The ultra-thin
IC card produced by using the ultrasonic embedding process is the
same as the IC card manufactured by the traditional process, so its
average service life will be longer than the ultra-thin IC card
produced by using the etching antenna (6 years) process. Two
different processes, the material difference is mainly in the
antenna part, the antenna material used in the etching antenna
process is a PET (polyethylene terephthalate, PET) sheet with a
thickness of 0.078 mm and a precision etched aluminum wire, and
Ultrasound embedding process antenna for enameled copper wire, the
same production performance of an IC card, according to the
material price of etching antenna price is about 2 times the price
of copper, so the use of ultrasonic embedding process to produce
ultra-thin IC card The price is also slightly better. The mass
production of ultra-thin IC CARDS will have a profound impact on
the continuous development of the smart card industry.
