Description
Technical field
The present invention relates to a kind of tooling device, relate in particular to a kind of device for correcting pin planeness of electron device, this pins arranging machine is that the pad that is used to adjust each pin of electronic device is in the same plane, so that be welded on the PCB surface reliably.
Background technology
At present, advanced electronic product, particularly at computer and communication class electronic product, the integrated circuit that is adopted (IC) has not had the jack components and parts, and particularly extensive, high integrated IC all adopts the surface patch components and parts; And these paster components and parts are installed to relevant position, PCB surface accurately, just need to adopt surface installation technique (Surface Mounting Technolegy is called for short SMT) to finish.
Typical surface mount process was divided into for three steps:---mounting components and parts---reflow soldering that applies solder(ing) paste.Promptly earlier an amount of solder(ing) paste is applied on the pad of PCB uniformly, to guarantee that paster components and parts and the corresponding pad of PCB when the reflow soldering, reach good electrical equipment connection, and have enough mechanical strengths; Then chip components and parts are mounted accurately the corresponding position, PCB surface of printed tinol; When then PCB being entered 140 ℃～160 ℃ preheating warm area, solvent, gas evaporation in the soldering paste fall, simultaneously, the wetting pad of scaling powder in the soldering paste, components and parts weldering end and pin, soldering paste is softening, slump, has covered pad, and pad, components and parts pin and oxygen are isolated; And make the surface patch components and parts obtain sufficient preheating, when then entering the weld zone, temperature rises to 270 ℃ rapidly makes soldering paste reach molten state, liquid scolding tin is in pad, components and parts weldering end and the pin diffusion of PCB, make that it is wetting, cross flow and backflow be blended in and generate metallic compound on the weld interface, forms the scolding tin contact; Last PCB enters the cooling zone solidifies solder joint.
But the normal because solder joint of each pin of components and parts that is mounted is not at grade, promptly the solder joint of all pins can not abut on the corresponding position, PCB surface simultaneously, like this after by reflow soldering, some pin is when tin cream melts, since the out-of-flatness of himself or unsettled, and make liquid solder can not soak into the pin of these components and parts, and the pin that causes cooling off the back components and parts can not be interconnected at by scolder with the PCB pad, and become rosin joint, influence product quality.In the prior art, for guaranteeing the evenness (making each pin in same plane) of each pin of components and parts, whether need first employing instrument to measure its each pin before mounting can recline at grade simultaneously, when finding to have the unsettled or out-of-flatness of pin, then be by manually reconciling its evenness with hand-operated tools such as tweezers.But only control with feeling owing to reconcile manually, adjustment is got up very difficult, problems such as consistency is bad, evenness is not good often occur; And manual operation takes a lot of work, time-consuming, production efficiency is low; Can't tackle the demand of product lot quantityization, the production automation.
Therefore, it is low by regulating efficient manually how to solve each pin evenness of this components and parts, and the problem that quality can't guarantee is those skilled in the art's contents of research emphatically.
