Description
Technical field
The invention belongs to plug-in mounting class device fixing device technical field on wiring board, be specifically related to one and be applicable to plug-in mounting unit device
Part carries out the stationary fixture of wave soldering.
Background technology
The welding method of electronic devices and components has: reflow soldering, wave soldering and three kinds of welding methods of manual welding, wave-soldering
Connect and mainly weld placing components, such as: resistance, electric capacity, transistor, integrated circuit, electric connector etc..Drawing of placing components
Foot is inserted to after shaping and shearing well in the upper respective pad hole of printed circuit board (abbreviation printed board), and placing components body is simply
It is placed in printed board, not yet in effect fixing, it is noted that keep level during printed board taking and placing, placing components otherwise can be caused
Pin is deviate from from plug-in mounting pad hole.During wave soldering, the printed board assembled is fixed in the placing trough of wave soldering device, moves
Dynamic printed board is at tin-lead solder plumb joint, and tin-lead solder forms one crest at plumb joint, has been come by movement printed board
Become the welding of plug-in mounting device.In welding process, the crest that tin-lead solder is formed is to be suppressed by the air pump of equipment to be formed, so ripple
There is a power upwards at peak, and this power easily by vertical component's feet jack-up, makes welding effect not reach in welding process
Wave soldering requirement.Multiple method is had to solve this problem at present: one, to be adhesively fixed by placing components with high temperature gummed tape, this
The shortcoming of method is: 1, high temperature gummed tape is relatively costly, and after substantially using twice, stickiness is inadequate, need to reuse new adhesive tape；2、
Bonding plane is difficult to select, and owing to placing components ambient conditions is more complicated, does not has suitable bonding plane just not reach adhesive effect；
3, easy damaged components and parts mark, after having welded, when removing high temperature gummed tape, easily sticks out components and parts mark, damages components and parts mark
Knowing, causing correctly cannot interpretation.Two, glue is bonding, and the shortcoming of this method is: 1, lengthen the production cycle, and some glue needs after completing
Want within 2～4 hours, hang, extend the production cycle；2, remove fixing glue difficulty, after having welded, fixing glue need to be removed,
Bottom resistance, electric capacity and audion, glue is difficult to remove.Three, fix with mould, for the mould that different printed board designs are corresponding
The fixing components and parts of tool, the shortcoming of this method is: 1, design cost is high, for different printed boards have for design mould,
Put into substantial amounts of artificial intelligence's cost；2, processing cost is high, and each printed board to make corresponding mould, for multi items
The production plant of small lot, mould finished product is higher.Four, pre-upper stannum, after plug-in mounting completes, enters one of them pin of placing components
Row welding so that it is being fixed in printed board, then carry out wave soldering, the shortcoming of this method is: 1, there is welding quality hidden danger,
After one the pre-upper stannum of solder joint completes, also want wave soldering, after wave soldering, also want repair welding, a solder joint multiple welding to there is welding
Hidden danger of quality；2, cost of labor increases, and each placing components will weld once, will put into the biggest cost of labor；3、
Reducing production efficiency, each placing components will weld once, increase the production time, elongate the production cycle.Therefore
It is necessary to propose to improve.
