Description
Technical field
The invention belongs to wave soldering of electronic product connection technology field, be specifically related to a kind of wave-soldering fixture and make rule
The method of model.
Background technology
The traditional design of electronic product is always emphasized desin speed and lists with Rapid Product, and ignores product
Manufacturability problem, then for correct product can manufacturing issue, need the redesign carrying out repeatedly,
Improving every time and will again make model machine, thus result in the design cycle long, cost is high, the most also delay product
The cycle put on market.
Electronic product totle drilling cost 60% depends on the initial design of product, and the manufacturing cost of 75% depends on design
Illustrating and design specification, the production defect of 70-80% causes due to design defect.Manufacturability design is just
It is from product development and design, just in view of manufacturability, is closely connected between making design and manufacturing, real
Now from being designed into manufacture once successful purpose.
There is various technique corresponding during electronic product welding, in wave soldering, fixture need to be had to support welding,
Guaranteeing welding spot reliability and protect electronic component, traditional welding method does not has working specification, welding
Efficiency is low, and welding effect is poor.
Summary of the invention
It is an object of the invention to provide a kind of method that wave-soldering fixture makes specification, reduce the one-tenth of wave-soldering
This, reduce the probability that deisgn product can not manufacture.
A kind of wave-soldering fixture makes the 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 component；
(2) selecting fixture direction, fixture is arranged at the narrow limit of wave-soldering；
(3) use piston and spring just fixture to fix, fixture is fixed in top bar, top bar bottom
It is provided with step (1) described circuit board；
(4) welding opening, preheats circuit board back, then uses the method for wave-soldering to weld, A/F
For 3.8-20mm, aspect ratio is 1: (1-3), and during welding, soldered circuit board with the angle of inclination of horizontal plane is
30°；
(5) on the pallet of circuit board, information flag is carried out；
(6) installing insert between the plug-in unit foot of circuit board, described insert is titanium insert, embedding
Method is the welding of two-sided plug-in unit；
(7) fixture is removed.
The information of step (5) described labelling includes: pallet number, supplier information, the serial number of pallet,
The section number of product, customer name.
The sidepiece of described top bar is additionally provided with locking.
The useful effect of the present invention: use the method for the present invention to prepare electronic devices and components, be welded into power high,
Manufacturability is strong, improves electronic product during wave soldering due to the abnormal welding caused of jig Design
Quality problem, does a manufacturability for welding engineering personnel and guides 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
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of wave-soldering fixture makes the 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 component；
The red sizing material of SMT uses authentic sizing material.
(2) selecting fixture direction, fixture is arranged at the narrow limit of wave-soldering；Carry out the vertical crest of thin space circuit board
During soldering, during choice direction, Small Distance element priority considers, avoids shadow effect to make element or torr simultaneously
Dish is placed in other elements.
(3) as it is shown in figure 1, use piston 1 and spring 2 just fixture to fix, fixture is fixed on top
On bar 3, top bar 3 bottom is provided with step (1) described circuit board 5；The sidepiece of described top bar is additionally provided with
Locking 4；The quantity of fixture relies on the design of PCB, and the distance between two fixtures is 2-3.5cm, fixture
Position should avoid contact to element or label.The suitably element arrangements of holding circuit plate and be fixed on crest
Weld, element arranges downwards and positions for guaranteeing that element correctly arranges on circuit boards, and different is downward
Location is the kind of the layout according to circuit board and element, and it is for setting element that edge positions downwards, as even
Connect device element.Movably should there be key mapping location to prevent dislocation.The height of location should be to have enough
Pressure be used on element, but can not ether tight.
(4) welding opening, preheats circuit board back, then uses the method for wave-soldering to weld, A/F
For 3.8-20mm, aspect ratio is 1: (1-3), and during welding, soldered circuit board with the angle of inclination of horizontal plane is
30-60°；The angle of inclination that fixture thick for 10mm uses is 30 °, the inclination that fixture thick for 8mm uses
Angle is 45 °, and the angle of inclination that fixture thick for 6mm uses is 60 °.
(5) on the pallet of circuit board, information flag is carried out；The information of described labelling includes: pallet number,
Supplier information, the serial number of pallet, the section number of product, customer name.Four limits of pallet should be provided with number
Sign is shown, fixture direction in soldering furnace should indicate.
(6) installing insert between the plug-in unit foot of circuit board, described insert is titanium insert, embedding
Method is the welding of two-sided plug-in unit；Insert can be used for protecting the surface mount elements being positioned in plug-in element, paster
Element is the thinnest, therefore, is exactly best selection for Titanium from the point of view of durability.
(7) fixture is removed.
