Plunger head style and Target objects suitable unsuitable depending on other conditions . Self cleaning PIN . BGA .. Pad Pin Thru CSP Soldering Other features Plunger head End of . Land Lead Hole Long lead point style Scratches . 1 .. If insulating coating is thin,it is resistance . Conical Depending is comparatively high because on it has only one point of contact. Loading When the target object is hard, contact resistance becomes stable if a heavier load is becomes stable when the target object is soft.. This style is used when you want to make it contact with the target Spherical object without scratching is Depending on suitable for coating with good Loading electric properties such as gold plating.. Flat Free This style does not make scratches on the target may become unstable if the target is hard.)

3 This style has a conical Borer Yes shape and addition, the heavier the load is,the more insulating coating is penetrated.. Note There are just rough standards,and they may vary depending on the material and shapes. 1-02.. Plunger head style and Target objects suitable unsuitable depending on other conditions . Self cleaning PIN . BGA .. Pad Pin Thru CSP Soldering Other features Plunger head End of . Land Lead Hole Long lead point style Scratches .. Circular cone Insulating coating can be pene- Yes trated because of this style has an acute becomes big if the target object is hard.. Insulating coating can be pene- Sharp Pointer trated because of this style has Yes an acute becomes big if the target object is hard. Contact resistance is comparatively high because it has only one point contact.. Free Make this contact with the target Concave object as if leading out its pin becomes unstable if insulating coating exists.. This style is used when there is Crown Depending a certain degree of insulating on Loading varies if the target object is hard.

Self cleaning PIN . BGA .. Pad Pin Thru CSP Soldering Other features Plunger head End of . Land Lead Hole Long lead point style Scratches .. This style is used when there is Sharp Crown Depending comparatively thick insulating on the target objects is Loading hard,abrasion occurs early and contact performance varies.. This style is used when there is Multipoint comparatively thick insulating Crown can be used for hard Depending target objects because it has on multipoint contact. Loading .. This style is used when there are more or less soldered parts or Reduced Crown Depending insulating coating on circuit on the target object is Loading hard,the resistance value become unstable depending on the number contact point.. Note There are just rough standards,and they may vary depending on the material and shapes.

5 1-04.. How to keep good contact with Spring probe pin.. 5,000 10,000 .. Precaution for use It is necessary to prevent dust accreting by sealing or covering when it is not used. It is also effective to cover entire equipment ,such as fixtures. Contact parts may be polluted because of little pieces of thread,cotton dust,cigarette in the room. If the room is closed and you wonder if it is clean,you need countermeasures and attention.. Plating fraction may fall off from target objects,such as pads,which plungers get contact adhere them. Remain of soldering flux on pc board also influences contact properties. Maintenance of Spring Probes To make Spring Probes last and gain good contact properties continuously,it is effective to do maintenance dependimg on the frequency of use,condition,and environment for preserving the initial performance. There are following maintenance factors..Exchanging Probes once every proper terms. (5000 to 10,000cycles is rough standard.)..Performing cleaning work.
