The skill of repaired thin wire

   PCB board patching is, generally in the line board patching process which determined according to the plate line diameter, we frequently uses is 4mil,6mil,8mil,10mil, 12mil and so on the application scope quite widespread lines, some lines below 4mil, speaking of make up the line, we are often smaller than the 4mil line to think is the fine lace, the fine lace in makes up in the line process the difficulty is quite big, specially regarding just started to use precise PCB to make up the line machine operator, made up the fine lace to reveal extremely strenuously, therefore, we summarized some skills in order to equipment training use.

    Must make up the fine lace, must practice the foot free time, the foot divides into steps on lightly, the spot steps on, the pressure steps on three kinds, welds the fine lace time, the foot free time plays the extremely vital role, usually after alignment sealed end, needs to put the line to above the line which must weld, because the line is extremely tiny, the match operation request is extremely high, specially the new operation staff, very easy to be able to have the vibration, therefore, with steps on lightly the method can assist the line presses in the spot position, this says regarding the novice has the significance extremely, regarding the skilled operator, lightSteps on also can enhance the alignment greatly the speed.

    If line already to good after, may use the method which the spot steps on to weld, because the line puts after, if has unnecessary touching again, possibly can enable it to deviate the original position, so long as therefore stepped on the direct welding to be possible, the spot stepped on the skill was settles on as far as possible, after was first slow steps on quickly presses online on.The pressure steps on in the welding curving place uses quite much, if usually this is not a weld point, but needs clings it online on time, needs to press steps on, the pressure steps on is the foot contracts the line, but not thrust augmentation welding, this is in the curve place the line localization best method.  Certainly, in the welding process also has some usually to weld the general line some skills, for instance puts when the line adopts the left hand to take the line as far as possible to put the line, the right hand takes the knife the method, the line the time which puts do not have to stretch out has grown, but also must downward press slightly little in order to paste the tight line.

    Next must finish the hand free time, hand free time one puts the line, one is moves the board, these two all are the demand time practices the skilled skill, the novice puts when the line may the screen live the breath, practices not to have first to tremble, the hand will not tremble later to be easy to do, the line was generally under presses from the spot left side, then made small about to move, stepped on the coordination through the foot, also aimed at around.

     During alignment, needs through to move the board to achieve the alignment the goal, moves the board method is, two palm of the hand skills depend on in the table surface are motionless, moves through the finger curving strength compaction line board.Because moves the distance is very small, needs to locate very precisely, the novice possibly thinks very difficultly, but so long as practices, could operate freely.

     Is once more the parameter choice, in the parameter the pressure factor all must be bigger than in the fine lace influence other lines, therefore needs to choose the appropriate pressure, suggested the customer chooses as far as possible can the accuracy control pressure make up the line equipment.The pressure appropriate judgment is in does not add the electric welding in the situation, steps on the trigger point, looks at the spot compressing situation, if can line slight compressing not as for the indentation depth, then for the appropriate pressure, this need operator tests certainly realized.

     Next is the welding voltage, the voltage oversized burns out easily the line, excessively small easy to weld not firmly, if this section power source is the output stable, then the welding voltage adjustable scope is very big, if is the voltage output insufficiently stable type, then welds the fine lace to discover frequently the parameter not good accent, the fine lace is very difficult to weld or the fine lace welding situation uneven performance, therefore, best can in selects and purchases in front of the equipment on carries on the appraisal to own welding demand, if needs to weld the fine lace under, then should suppress the heart to purchase good, precise equipment.The time affects generally not not in a big way, but is opposite in the medium line needs the scope which and small can weld appropriately slightly quite to be small.Mainly decided according to the welding basis situation.

    The above is welds the fine lace some methods, so long as operates according to the method, can reduce in very many weldings the worry, welds the fine lace is the process which makes one have a headache, but so long as has grasped skill.The fine lace welding also can change relaxedness.
