Description
Technical field
The present invention relates to the light shields of the analysis of spectrum solder joint and imaging after a kind of wave-soldering.
Background technique
Wave-soldering is to allow the welding surface of card directly to contact with high-temperature liquid state tin to reach welding purpose, high-temperature liquid state tin
An inclined-plane is kept, and so that liquid tin is formed the phenomenon that a lot of is similar to wave by special device, so being " wave-soldering ", is led
Wanting material is soldering tin bar.Wave-soldering refers to the solder (terne metal) of fusing, through electrodynamic pump or electromagnetic pump jet flow at setting
Desired solder wave is counted, can also be formed by injecting nitrogen to solder pot, pass through the printed board for being pre-loaded with component
Solder wave realizes component welding end or pin and the room machine of printed board pad and the solder of electrical connection.Wave-soldering stream
Journey: element is inserted into corresponding component hole → pre-coated soldering flux → preheating (90-100 DEG C of temperature, length 1-1.2m) → wave crest
Weld the extra plug-in unit foot → inspection of (220-240 DEG C) cooling → excision.Reflow soldering process is to allocate print in advance by refuse
Paste solder on making sheet pad realizes the room machine and electricity of surface-assembled component welding end or pin and printed board pad
The solder of gas connection.Wave-soldering has new welding procedure to the enhancing of environmental protection consciousness with people.Pervious is to adopt
With leypewter, but lead is that heavy metal has very big injury to human body.Then growth-promoting lead-free process, using Tin Silver Copper Alloy
With special scaling powder, and the higher preheating temperature of requirement of welding temperature.Miniaturization and powerful is not needed most of
Still perforation (TH) or mixing technical route plate, such as television set, family's audio and video equipment and teaching machine top are being used on product
Box etc., still all with punctured element, it is therefore desirable to use wave-soldering.From technological angle, wave soldering machines can only be provided
Seldom any most basic equipment operating parameter adjustment.After wiring board enters crest welder by conveyer belt, some can be passed through
The scaling powder applying device of form, scaling powder is coated on wiring board using wave crest, foaming or the method for injection herein.Due to
Most of scaling powders have to reach in welding and keep an activation temperature to guarantee the complete wetting of solder joint, therefore route
Plate will first pass through a preheating zone before entering wave crest slot.Preheating after scaling powder coating can gradually promote the temperature of PCB
And scaling powder is activated, this process can also reduce assembly and enter the thermal shock generated when wave crest.It can also be used to evaporate
Fall all possible moisture absorbed or dilute the carrier solvent of scaling powder, if these things are not removed, they can be
It boils when crossing wave crest and scolding tin is caused to sputter, or generate steam and stay in the solder joint or sand holes that formation is hollow inside scolding tin.In addition,
Since dual platen and multiple-plate thermal capacity are larger, they need higher preheating temperature than single sided board.
