It is often that golden finger is set in FPC both sides, FPC is welded by golden finger and external devices, to reach the purpose of electric connection.
Authorization Notice No. is that CN204119655U Chinese utility model patent discloses a kind of golden finger position hollow out
Multi-layer flexible circuit board, the FPC offer the connection window of hollow out in the position of golden finger, and FPC is connecing
When entering external devices, the connection window position of hollow out need to be only set in the access golden finger position of external devices, make flexible wires
The golden finger of road plate is correspondingly covered on the access golden finger of external devices, is then welded, and this mode can increase
Add the solder attachment area between the golden finger between FPC and external devices, strengthen welding stability, make welding more
Add firmly, and it is convenient welding, simple, quick.
For the higher thick copper hollow out golden finger class FPC of hardness, during production process and follow-up SMT, easily
Influenceed by environment such as air humidity and temperature changes and expand or shrink.FPC expansion or contraction can influence its precision,
There is such as solder joint and pull not connecting or the situation of loose contact, and then cause product failure to be scrapped.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of thick copper foil with hollow out golden finger
Orthopedic FPC, it is unlikely to deform FPC by orthotic structure.
The utility model is to solve the technical scheme that its technical problem uses to be：
A kind of orthopedic FPC of thick copper foil with hollow out golden finger, including base material, the copper foil circuit and gold that are printed on base material
Finger, the golden finger are arranged at the both sides of base material, and the golden finger has the inner being connected with circuit and extends to base material side
The outer end of edge, the FPC are provided with the concave station rank being stamped and formed out in golden finger area, and the inner end portion of the golden finger remaines in
On the inner side base material of concave station rank, the base material corresponds to recessed stepped portions and is provided with the hollow out for only retaining golden finger figure.
Further, it is provided with intermediate incline on the inside of the concave station rank.
Further, the hollow out extends to the outer end of golden finger.
Further, the copper foil circuit is formed by etching.
Further, the copper thickness is 4oz to 8oz.
The beneficial effects of the utility model are：A kind of orthopedic FPC of thick copper foil with hollow out golden finger of the present utility model,
The concave station rank being stamped and formed out in the golden finger area of its both sides, thus release FPC stress is orthopedic to carry out, and makes thick copper FPC
Expansion or contraction distortion are not easy, avoiding during varying environment use product solder joint from pulling causes bad connection, carries simultaneously
High product reliability, cost is saved, improved client's credit worthiness.
Brief description of the drawings
Fig. 1 is top view of the present utility model；
Fig. 2 is front view of the present utility model.
Embodiment
The utility model is described further below in conjunction with accompanying drawing and example.
As depicted in figs. 1 and 2, a kind of orthopedic FPC of thick copper foil with the golden finger of hollow out 4 of the present utility model, including base material
1st, the copper foil circuit 2 and golden finger 3 being printed on base material 1, the copper foil circuit 2 are formed by etching.The golden finger 3 is set
The both sides of base material 1 are placed in, the golden finger 3 has the inner being connected with circuit and the outer end for extending to the edge of base material 1, described
FPC is provided with the concave station rank 5 being stamped and formed out in the region of golden finger 3, to reach orthopedic effect.The utility model passes through concave station rank 5
FPC internal stress is discharged, thick copper FPC is not easy expansion or contraction distortion, avoids the product during varying environment use from welding
Point, which is pulled, causes bad connection, while improves product reliability, has saved cost.
The inner side of the concave station rank 5 is provided with intermediate incline 6, avoids the drop of concave station rank 5 big and causes golden finger 3 to damage
Wound.
The inner end portion of the golden finger 3 is remained on the inner side base material 1 of concave station rank 5, it is ensured that the company of golden finger 3 and circuit
Connect reliable.
The corresponding position of concave station rank 5 of base material 1 is provided with the hollow out 4 for only retaining the figure of golden finger 3, by golden finger 3 in recessed
The blank space of step 5, which is punched, to be removed.The hollow out 4 extends to the outer end of golden finger 3, facilitates golden finger 3 to be welded with external devices
Connect.
The copper thickness is preferably 4oz to 8oz.
Thick copper foil orthopedic FPC of the present utility model with the golden finger 3 of hollow out 4 can use following technique to make, and step is as follows：
