Further, the connecting plate pad is with the pore structure through connection pad.
Further, the pore structure is the ellipse of 0.45*0.9mm.
Further, width 0.2mm of the width of the limiting slot than connecting pin pin, the thickness ratio of limiting slot
Connect the thickness thickness 1mm-2mm of pin pin.
The connection structure of the low-and high-frequency pcb board of various embodiments of the utility model, due to including mainly：Pin pin is connected, is used
In connection frequency PCB and low frequency PCB；Connecting plate pad, for connecting pin pin；With the limiting slot being arranged in supporting carrier,
For being limited to the connection pin pin in welding process；The connection pin pin is L-shaped；So as to promote back segment weldering
The quality of the efficiency and improvement human weld that connect.
Other features and advantages of the utility model will illustrate in the following description, also, partly from specification
In become apparent, or understood by implementing the utility model.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not constitute limitations of the present invention together.In the accompanying drawings：
Fig. 1 is that the prior art linear described in the utility model embodiment connects pin pin structural schematic diagrams；
Fig. 2 is the structural schematic diagram of the L-shaped connection pin pin described in the utility model embodiment；
Fig. 3 is the connection pad with pore structure described in the utility model embodiment；
Fig. 4 is the composite unit structure schematic diagram of the limiting slot and carrier described in the utility model embodiment；
Fig. 5 is the combining structure schematic diagram of L the types pin and pad described in the utility model embodiment.
In conjunction with attached drawing, reference numeral is as follows in the utility model embodiment：
1- positive stop strips；2- limiting slots；3- supporting carriers.
Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
The utility model takes following technical scheme：
1. redesigning the thickness of connection pin（Current product, best thickness are 0.12-0.15mm）, thickness to the greatest extent may be used
Thinning, the stress after reduction welding of energy.Because after pin thickness is thinning, bending is easy in the processing procedure of supplier, have when locally
When stress, material can be bent, and be reduced to damage
2. redesigning the shape of connection pin, l-shaped is designed by linear type（Such as Fig. 2）, given birth to when being matched with corresponding pad
When production, prevent situations of the pad by stress damage, it is specific such as schematic diagram
3. redesigning the pad for connecting pin on high frequency plate or low frequency plate, by the smooth pad of SMT, it is changed to hole peace
The combination of face pad, specific such as schematic diagram 3, the size of the borehole on PAD, hole are determined according to the width and thickness of pin, at present not
The technique effect of the ellipse of 0.45*0.9mm, acquirement is：Enhance the weld strength of pin and PAD.
4. during actual verification, L-type pin occurs to make due to the pulling force of tin cream during SMT reflow solderings
At the bad phenomenon of left and right offset, Computer Aided Design pin limits carrier, i.e. limiting slot, is carried in support according to the thickness and width of PIN
The limiting slot designed on tool prevents pin or so shift phenomenons, specific such as schematic diagram.
Wherein supporting carrier is carrier, and all actions are completed on it；
Positive stop strip, in combination on carrier, above there are many limiting slots；
On positive stop strip, positive stop strip is assembled on carrier limiting slot.
5.L types pin at SMT sections first by machine patch on the pad for being changed to hole and plane pad combinations, by stove
Reflow soldering is specific such as schematic diagram 5 on plank.
6. the other end assembles section in FA, it is welded on other one piece of plank using automatic welding machine
Following advantageous effect can at least be reached：
1.L types pin uses Placement, improves the efficiency of production
2. material is thinning, the expense of material is saved
The welding of 3.L types Pin is welded using Reflow Soldering and automatic welding machine, improves the quality of welding
The entire production of 4.L types Pin is entirely machine attachment and welding, saves manpower
The change of the design of 5.L type pin pad reduces the pad crack risks after welding
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
