Description
Technical field
The invention belongs to wave soldering scaling powder atomization technique field, it is good and have a soldering flux spraying system for wave soldering of less noise to be specifically related to a kind of atomizing effect.
Background technology
Wave soldering for the effect by pump of the liquid solder of fusion, forms the solder crest of a given shape at the solder liquid level, and the PCB that has loaded components and parts is with a certain special angle, and passes the solder crest with certain immersion depth and realize the brazing filler metal process of solder joint.Because wave soldering labor and material saving, improved production efficiency, reduced production cost, quality of welding spot and reliability have been improved, do not need to use on the product of miniaturization perforation (TH) or mixed technical route plate at great majority, such as television set, family's audio and video equipment and be about to the top box of digital machine released etc., need use wave-soldering.
Wiring board enters by conveyer belt after the crest welder, can be through the scaling powder applying device of certain form, and here scaling powder utilizes the method for crest, foaming or injection to be coated on the wiring board.Because most of scaling powders the time must reach and keep an activation temperature to guarantee the infiltration fully of solder joint in welding, so wiring board is wanted earlier through a preheating zone before entering the crest groove.Preheating after the scaling powder coating can promote the temperature of PCB gradually and make the scaling powder activation, and this process can also reduce the thermal shock that produces when assembly enters crest.It can also be used to evaporating the carrier solvent of the moisture that might absorb or dilution scaling powder, if the not removed words of these things, they can seethe with excitement when crossing crest and cause the scolding tin sputter, perhaps produce steam and stay solder joint or the sand holes that the scolding tin the inside forms hollow.The length of crest welder preheating section is decided by output and line speed, and output is high more, just needs longer preheating zone for making plank reach required infiltration temperature.In addition, because dual platen and multiple-plate thermal capacity are bigger, so they need higher preheat temperature than single sided board.
The scaling powder coating unit has certain technical requirements, as requires the coat uniformity that obtains, and is good to soldered spreadability; The thickness that applies is suitable, coating efficiency height, good environmental protection etc.In order to reach these requirements, scaling powder coating unit commonly used at present is the spray application system.General at present use atomizing helps the weldering system, adopts no-clean scaling powder, and this is that non-volatile no content has only 1/5～1/20 because solids content is few in the no-clean scaling powder.So must adopt atomizing to help the weldering system to apply scaling powder, in welding system, add simultaneously anti-oxidation system, guarantee on PCB, to obtain evenly fine and closely woven very thin scaling powder coating of one deck, so just can be because of the volatilization of the scrubbing action and the scaling powder of first ripple, cause the scaling powder quantity not sufficient, and cause the scolder bridge joint and draw point.Atomizing has dual mode: the one, and adopt ultrasonic wave to impact scaling powder, its particle is diminished, spray on the pcb board again.The 2nd, adopt the minute nozzle scaling powder of under certain air pressure, spraying.This spraying is even, granularity is little, is easy to control, and spray height/width can be regulated automatically.Yet, in the prior art spraying system is carried out Stroke Control, and circuit board is accurately located spraying solution is not preferably arranged as yet.In addition, current scaling powder atomizing system exists atomizing effect instability, the vibrations of whole service unit and noise is bigger than normal, mist flow is unstable and optional nozzle types is comparatively single etc. has bad factor to exist for the welding plank.The present invention is in order to solve these defectives.
