Description
Technical field
This utility model relates to electronic product machining technical field, is specifically related to a kind of New LED and drives power supply.
Background technology
Along with electronic technology is development with rapid changepl. never-ending changes and improvements, it is fewer and feweri for can seeing lead-in wire electron-like element in current electronic product, and increasing product employs the element of paster mounting means.Surface mount elements has many benefits compared with lead elements and production method thereof, as little in volume, lightweight, save PCB space, be more easily installed than lead elements and production method thereof and dismantle, can reduce the advantage such as stray electric field and stray magnetic field, the stability that improve circuit and reliability.
But the welding of surface mount elements needs certain experience and technical ability;Owing to most surface mount elements volume is little, lightweight, location inconvenience during welding, this may result in wrong weldering or solder skip unless you give your whole attention to it, it is also possible to the situation that in appearance, stannum is too much;Especially when welding intensive multi-pipe pin patch chip, it is easy to cause the bipod even multiway of chip by chip by scolding tin short circuit.For the abecedarian of just introduction, often " fear " is felt in surface mount elements welding operation, think that it is prone to welding unlike traditional direct plug-in element and holds.In conjunction with domestic industry development present situation, described phenomenon brings the cost pressure of the aspect such as personnel recruitment and staff training to electronic product manufacturer, also counteracts that further improving product qualification rate and the life cycle of product.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and this utility model provides a kind of New LED to drive power supply, by arranging some step grooves on pcb board, helps welder to position surface mount elements;The phenomenon that wrong weldering, solder skip and scolding tin are too much is stopped by arranging del block tin.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of New LED drives power supply, including the power input being positioned on pcb board, power output end, driving chip, input electrochemical capacitor, energy storage chip inductor, electric fuse resistance, output electrolytic capacitor filter;It is anterior that described electric fuse resistance is positioned at power output end, described input electrochemical capacitor is between power input and driving chip, described energy storage chip inductor is between driving chip and output electrolytic capacitor filter, and described power output end is connected with output electrolytic capacitor filter;Described pcb board is provided with some step grooves for installing patch electronics element;Being provided with cushion bottom described step groove, top is provided with del block tin.
Improving further as this utility model, described step groove is circular trough or rectangular channel.
Improving further as this utility model, described cushion is rubber layer.
Improving further as this utility model, described cushion upper surface is convex shape, and lower surface is plane.
Improving further as this utility model, the thick size degree of described cushion is slightly larger than the depth dimensions bottom step groove.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
The New LED of this utility model scheme drives power supply, by arranging some step grooves on pcb board, helps welder to position surface mount elements;The phenomenon that wrong weldering, solder skip and scolding tin are too much is stopped by arranging del block tin;Such scheme both can improve survival rate of products and conforming product rate, can reduce again the labor intensity of cost of labor consumption and welding personnel, it is also possible to improves the service life of LED drive power.

Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of New LED as shown in accompanying drawing 1 to accompanying drawing 2 drives power supply, including the power input being positioned on pcb board 1, power output end, driving chip, input electrochemical capacitor, energy storage chip inductor, electric fuse resistance, output electrolytic capacitor filter.
For alleviating the labor intensity of welding operator, stopping the phenomenon that wrong weldering, solder skip and scolding tin are too much, above-mentioned pcb board 1 is provided with some step grooves 4 for installing patch electronics element;Being provided with cushion 5 bottom described step groove 4, top is provided with del block tin 2.
The specific operation process of present embodiment is as follows:
First surface mount elements is put into step groove 4, and the size of step groove 4 size according to concrete surface mount elements when pcb board 1 designs determines;Step surface 3 in step groove 4 covers one layer of scolding tin in advance;The pin portions of surface mount elements is directly placed on the scolding tin of step surface 3, owing to the thickness of cushion 5 is slightly larger than the depth dimensions bottom step groove, therefore when the main part of surface mount elements presses on cushion 5, cushion 5 can deform, and can produce a resilience force upwards.Use instrument is now needed to push down cushion 5 so that keeping the elastic force back up of cushion 5.
Del block tin 2 is broken to rear polar sites 22, start reflow machine or triangle block tin 2 is slowly melted by high temperature welding gun, and the liquid solder making thawing produce the most uniformly drips and covers the pin portions of surface mount elements.Removing reflow machine or high temperature welding gun stands, after a period of time, soldering tin binds is complete, and instrument of pushing down is removed, and checks surface mount elements welding machine situation: if also del block tin 2 exists, illustrate that solder skip phenomenon occurs in corresponding position;Because of the existence of the elastic force back up of cushion 5, if surface mount elements has substantially tilts phenomenon, illustrate that rosin joint phenomenon occurs in corresponding position;Because the concrete volume of del block tin 2 is certain, it can be ensured that do not have the phenomenon that scolding tin is too much.
Further, del block tin 2 can be broken to front extreme position 21 when surface mount elements is put in step groove, put into surface mount elements to facilitate.
Further, step groove can be set to circular trough or rectangular channel as required.
Due to the existence of step groove 4, can very easily all surface mount elements be positioned.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
