Abstract
The invention belongs to the technical field of wave-soldering of electronic products and discloses a method for standard manufacturing of a wave-soldering fixture. The method includes the steps of selecting a circuit board, selecting the direction of the fixture, fixing the fixture, welding an opening, marking a tray, installing an insert and the like. Electronic components manufactured through the method are high in welding success rate and high in manufacturability; the problem that welding quality of the electronic products is poor due to abnormal designs of the fixture in the wave-welding process is solved, and the method can guide welding engineers on the aspect of manufacturability in the process of fixture designs.
Description
Technical field
The invention belongs to wave soldering of electronic product connection technology field, be specifically related to a kind of method that wave-soldering fixture makes specification.
Background technology
The traditional design of electronic product is always emphasized desin speed and is gone on the market with Rapid Product, and ignore the manufacturability problem of product, so can manufacturing issue in order to what correct product, need the redesign carried out repeatedly, each improvement all will make model machine again, therefore cause the design cycle long, cost is high, simultaneously also delay product cycle of putting on market.
Electronic product totle drilling cost 60% depends on the initial design of product, and the manufacturing cost of 75% depends on specification and design specification, and the production defect of 70-80% causes due to design defect.Manufacturability design is exactly from product development and design, just considers manufacturability, make to be closely connected between Design and manufacture, realizes from being designed into manufacture once successful object.
Have various technique corresponding during electronic product welding, in wave soldering, need have fixture to support welding, guarantee welding spot reliability and protect electronic component, traditional welding method does not have working specification, and welding efficiency is low, and welding effect is poor.
Summary of the invention
The object of the present invention is to provide a kind of wave-soldering fixture to make the method for specification, reduce the cost of wave-soldering, reduce the probability that deisgn product can not manufacture.
Wave-soldering fixture makes a method for specification, comprises the steps:
(1) select have the single-sided circuit board of PTH element or bottom to have red glue to enclose the circuit board of SMT element;
(2) select square fixture to, fixture is arranged at the narrow limit of wave-soldering;
(3) adopt piston and spring just fixture fix, be fixed on by fixture in top bar, top bar bottom is provided with step (1) described circuit board;
(4) weld opening, preheat circuit backboard portion, then adopt the method for wave-soldering to weld, A/F is 3.8-20mm, and aspect ratio is 1: (1-3), and during welding, the angle of inclination of soldered circuit board and horizontal plane is 30 °;
(5) on the pallet of circuit board, information flag is carried out;
(6) between the plug-in unit pin of circuit board, install insert, described insert is titanium insert, and the method for embedding is the welding of two-sided plug-in unit;
(7) fixture is removed.
The information of step (5) described mark comprises: pallet number, supplier information, the sequence number of pallet, the section number of product, customer name.
The sidepiece of described top bar is also provided with locking.
Useful effect of the present invention: adopt method of the present invention to prepare electronic devices and components, be welded into power high, manufacturability is strong, improving the welding quality problem that electronic product causes because jig Design is abnormal in wave soldering process, guiding for welding engineering personnel do a manufacturability when designing fixture.
Accompanying drawing explanation
Fig. 1 is fixture fixed structure schematic diagram;
In figure, 1-piston, 2-spring, 3-top bar, 4-locking, 5-circuit board.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Embodiment 1
Wave-soldering fixture makes a method for specification, comprises the steps:

(2) select square fixture to, fixture is arranged at the narrow limit of wave-soldering; When carrying out the vertical crest soldering of thin space circuit board, during choice direction, Small Distance element priority is considered, avoids shadow effect to make element or pallet be placed in other elements simultaneously.
(3) as shown in Figure 1, employing piston 1 and spring 2 just fixture are fixed, and be fixed on by fixture in top bar 3, top bar 3 bottom is provided with the described circuit board 5 of step (1); The sidepiece of described top bar is also provided with locking 4; The quantity of fixture relies on the design of PCB, and the distance between two fixtures is 2-3.5cm, and the position of fixture should be avoided touching element or label.The element arrangements of suitable holding circuit plate and be fixed on wave soldering place, element arranges downwards and location is used for guaranteeing that element correctly arranges on circuit boards, different downward location is the kind of layout according to circuit board and element, and it is for setting element that edge is located downwards, as connecting element.Should there be key mapping moveable location to prevent dislocation.Location height should be used on element to have enough pressure, but can not ether tight.
(4) weld opening, preheat circuit backboard portion, then adopt the method for wave-soldering to weld, A/F is 3.8-20mm, and aspect ratio is 1: (1-3), and during welding, the angle of inclination of soldered circuit board and horizontal plane is 30-60 °; The angle of inclination that the fixture that 10mm is thick adopts is 30 °, and the angle of inclination that the fixture that 8mm is thick adopts is 45 °, and the angle of inclination that the fixture that 6mm is thick adopts is 60 °.
(5) on the pallet of circuit board, information flag is carried out; The information of described mark comprises: pallet number, supplier information, the sequence number of pallet, the section number of product, customer name.Four limits of pallet should be provided with figure denote, and the direction of fixture in soldering furnace should indicate.
(6) between the plug-in unit pin of circuit board, install insert, described insert is titanium insert, and the method for embedding is the welding of two-sided plug-in unit; Insert can be used for protecting the surface mount elements being arranged in plug-in element, and surface mount elements is very thin, therefore, is exactly best selection for durability Titanium.
(7) fixture is removed.
