Description
Technical field
The utility model relates to the board structure of circuit technical field, particularly relates to a kind of pcb board and electronic equipment.
Background technology
Direct inserting device is exactly pin and need to be at the PCB(printed circuit board (PCB), PrinT1ed CircuiT1 Board) punching is installed on the plate device, generally its device body is at the components and parts face of pcb board, and its pad is at the solder side of components and parts face.For example, piezo-resistance is exactly a kind of direct inserting device.
The assembling process of direct inserting device on pcb board is: at first direct inserting device is inserted in the insert hole of pad on the pcb board, then adopt wave-soldering that the pin of direct inserting device is welded in the insert hole of pad, in the welding process of certain pin of direct inserting device, liquid solder is filled up from the solder side of pcb board by the insert hole at this pin place, relies on gravity and capillarity that scolder is filled in the pin of direct inserting device and the gap of insert hole.
The pin of direct inserting device has various structures.Which kind of pin configuration no matter because the restriction of machining accuracy, the pin-pitch of part direct inserting device (distance between the direct inserting device adjacent leads center line) is larger, for example the pin-pitch tolerance industry general control of piezo-resistance+/-1mm or more than.
At present, the pin for direct inserting device designs independently circular inserts hole usually, and the aperture in circular inserts hole is usually only than the large 0.2 ~ 0.6mm of leg diameter of direct inserting device.Like this, in the pin-pitch of direct inserting device be+/-1mm, and in the yielding situation of pin, the pin-pitch of direct inserting device often exceeds pitch of holes specification on the pcb board, will cause the plug-in mounting difficulty of direct inserting device.With reference to Fig. 1, show the plug-in mounting schematic diagram of a kind of direct inserting device of prior art, the pin-pitch of direct inserting device is large more more or little more than circular inserts pitch of holes on the pcb board 100, and two pins 101 that all can cause direct inserting device are simultaneously in the smooth and easy reeve circular inserts hole 102.
If directly the aperture with the circular inserts hole changes greatly, can partly solve the plug-in mounting difficult problem of direct inserting device, but can cause new weld defect problem.The inclusion enclave of its device body of some direct inserting device (such as piezo-resistance) can partly wrap up two pins, the part that direct inserting device body inclusion enclave partly wraps up pin, porcelain body herein, be commonly referred to the shoulder of direct inserting device, the shoulder of direct inserting device is usually tapered, because it is large that the aperture in circular inserts hole becomes, the shoulder of direct inserting device easily injects in the circular inserts hole and the circular inserts hole is blocked; On the one hand, the lower surface in circular inserts hole is immersed in the scolder of melting in the welding process, and the air in the circular inserts hole can't be discharged from the pcb board upper surface, thereby forms Xi Dong at solder side; On the other hand and since the nonwetting decision of shoulder of direct inserting device its can not form effective solder joint, therefore the shoulder of direct inserting device injects the vertical filling that easily affect through hole in the circular inserts hole, the porcelain body in the inserting hole is partly more, the vertical filling of through hole is just poorer.Above-mentioned Xi Dong, vertical lack of fill are weld defect.
Therefore, plug-in mounting difficult problem and the weld defect problem of direct inserting device can not be resolved simultaneously at present.
