Wherein, the material of the carrier is made from high molecular polymer and one edge of the carrier is provided with a slot. Thereby, the carrier can achieve the effects of tough structure, easy manufacture and positive positioning of the printed circuit card.
Description
Technical field
The utility model relates to a kind of improved miniature printed circuit board carrier, particularly with a kind of structure printed circuit board (PCB) carrier structure-improved tough, easy to make and that firmly miniature printed circuit board is located that reaches.
Background technology
General minitype circuit board is before crossing the tin stove, circuit board must be fixed on the carrier, again carrier is placed on the slide rail of tin stove and move, and utilize the scolder liquid in the tin stove to produce plural number time tin ripple, directly be attached to the weld pad place of electronic building brick stitch on the circuit board, so that the stitch of electronic building brick is the fixing state of a welding in circuit board, to finish the flow process that this crosses the tin stove.Yet, though but known minitype circuit board carrier bearer circuit plate made the tin stove, include many great shortcomings.
See also Fig. 1, be the outer sight schematic diagram of known miniature printed circuit board carrier, as shown in the figure:
The main material of known carrier 1 is wooden, and its structure is made up of a base plate 11, two retaining tin limits 13 and two rib limits 14.Wherein, on base plate 11, dig hollow slots 12 required when being provided with the welding of some fit printed circuit board electronic building brick pins, and install a wooden ground in addition in base plate 11 belows, make part hollow slots 12 bottoms be subjected to wooden ground sealing and formation recess 15, this electronic building brick for projection on the fit printed circuit board is established.The function on retaining tin limit 13 and rib limit 14 is respectively to prevent that scolder liquid from splashing and get to printed circuit board (PCB) and printed circuit board (PCB) is located.So, this carrier 1 structure contains following shortcoming:
1. be difficult for making:
When making carrier, the size of the necessary measurement of process earlier printed circuit board (PCB) row cooperation is again made, so when digging recess, because its wooden material method system of digging one thin recess, so must add a ground again in thereafter after the hollow out, form recess, cause the complicated and difficult making of step.
2. can't dig the hollow slots of special requirement:
Because wooden structures rigidity deficiency, if each hollow slots distance of desiring to dig is too near, then the rib between each hollow slots will be because of meticulous easy fracture, so can't dig the hollow slots of special requirement.
3. heatproof is not high:
The flow process of crossing the tin stove is to be carried out at the condition of high temperature, and wooden material can't have efficiency high temperature resistance, easily causes damage.
4. easily cause damage because of processing:
Printed circuit board (PCB) is in adding the chemical liquid that can add some strong acid or highly basic man-hour, as etching liquid medicine etc., and carrier can't resist strong acid and strong base because of its wooden material, can be corroded or carbonization after therefore using a period of time, and its rigidity deficiency is easily damaged because of being subjected to clashing into.
5. can't really printed circuit board (PCB) be located:
When crossing the tin stove, the rib limit of carrier can't be really with the printed circuit board (PCB) location, must get a weight in addition and be pressed on the printed circuit board (PCB) top and make it firm, right ballast is when shake is big, also printed circuit board (PCB) can't be located really, and printed circuit board (PCB) may be damaged by pressure.
Because the shortcoming of known miniature printed circuit board carrier, it is not perfect to attaining for the design people's thoughts, then exhaust intelligence, concentrated research overcomes, with being engaged in the experience accumulation for many years of this industry, and then develop a kind of improved miniature printed circuit board carrier, use the shortcoming of improving above-mentioned known configurations.
Summary of the invention
The main technical problems to be solved in the utility model provides a kind of improved miniature printed circuit board carrier, and it is tough to reach structure, not the effect of corrosion-vulnerable and damage.
Another technical problem to be solved in the utility model provides a kind of improved miniature printed circuit board carrier, can reach to make simple and can produce the effect of various special hollow slots.
Another technical problem to be solved in the utility model provides a kind of improved miniature printed circuit board carrier, can reach the effect of really printed circuit board (PCB) being located.
For reaching above-mentioned purpose, technology of the present utility model is achieved as follows:
A kind of improved miniature printed circuit board carrier can carry miniature printed circuit board and make the tin stove, and wherein, the material of this carrier is a high molecular polymer, and the one side is provided with slot.
Aforesaid improved miniature printed circuit board carrier, this high molecular polymer can be any combination in PP and carbon fiber, PE and carbon fiber and PT and the carbon fiber.
The utility model has also proposed a kind of improved miniature printed circuit board carrier, and its main material is a high molecular polymer, and this carrier comprises:
One base plate;
Keep off the tin limit, be located at two ends of this base plate;
Some ribs limit is located between in addition two ends of this base plate, Yi Bian and bottom, two adjacent ribs limits be provided with slot at least.
Aforesaid improved miniature printed circuit board carrier, this high molecular polymer can be any combination in PP and carbon fiber, PE and carbon fiber and PT and the carbon fiber.
Aforesaid improved miniature printed circuit board carrier, this carrier can be by this some ribs limit arrangement, form " mouth " font, " day " font, " order " font with and derive in the shape any.
By this, the utility model can overcome the shortcoming of known configurations, have make simple and easy; Structure is strong and unyielding, is applicable to various special requirements; High temperature resistant, durable; The advantage that can really miniature printed circuit board be located.
