The market development trend of SIM card holder with three options, two in one and a card tray

  In the development of the terminal market field, more and more people choose the multi-function dual-card
slot with three options and two-in-one SIM card holder. With the continuous innovation and upgrading of
communication electronic products, more and more products will give priority to the use of multi-function
card slots in order to save space. One SIM card holder, the types of SIM card holders commonly used by
CARDCONN electronic are: SIM NANO+NANO+TF three choices two, SIM MICRO+NANO+TF three choices two,
SIM Nano+Nano+ TF three-choice three-card holder, NANO SIM card holder with card tray, MICRO SIM card holder
with card tray, waterproof NANO SIM card holder with card tray, SIM card holder 6+2PIN drawer type with
card holder, etc. Now we are very concerned about the product The use performance is constantly being
upgraded and improved. Manufacturers should also keep pace with the times and continuously update products.
The volume requirements for many communication electronic products are also getting smaller and smaller,
and the size of the SIM card is greatly reduced to avoid being too much. Space occupation, in order to
facilitate the use of the above all-in-one SIM card holder, the SIM card holder manufacturer also configures
the corresponding card tray for easy use.
  CARDCONN SIM card holder product features:

  1. The contact performance of the spring card is good: the terminal is gold-plated and the contact performance
of the spring card is good, and the contact is still good after 5000 uninterrupted plugging and unplugging.

  2. High solderability and flatness: dip the tin feet in the tin furnace at ±255°C for 5.5 seconds.
The surface sticking tin area is not less than 99.5%. The reflow soldering temperature is 255±5°C.


Method for making SIM card holder with three options and two in one
The patent application for the electronic
component connector market discloses a SIM three-choice two card holder, which is composed of NANO, MICRO,
and TF card holders, including an insulating body, three conductive terminal groups formed on the insulating body,
A shielding case covering the terminal group, and a drawer seat that can be pushed and pulled between the shielding
case and the terminal group, the drawer seat includes three card receiving slots, two of which are overlapped ,
the two overlapping card receiving slots are respectively the TF card slot and the first SIM card slot, and the
other card slot is the second SM card slot. The projections of the first top card slot and the second SIM card slot
in the card insertion direction coincide, so that the contact parts of the conductive terminals of the two SIM card
terminal groups are in the projection overlapping position. When the drawer seat accommodates two SIM cards, during
the insertion/extraction process, the gold finger of the SIM card on the front side of the card insertion direction
needs to rub the contact portion of the conductive terminals of the two SIM card terminal groups, As a result,
the golden finger of the SIM card on the front end side is unable to recognize the card due to excessive wear and tear.
