Standardization of Soldering Quality

Soldering for retrofit parts has problems such as solder bridging, solder ball spattering and cold solder so that stabilizing of soldering quality is difficult.

BECAUSE

  1. 1

    There are many factors making
    soldering to be difficult as followings :
    Differences in workers’ skills
    Differences in parts quality
  2. 2

    Difficult factors for
    automatic soldering machines:
    Worn out of soldering tips
    Unstable heat supply
    Unstable solder amount

To solve these problems, Cosmic invented “Cut and Solder System” of PSU500 Automated Point Soldering Robot System.

We have successfully managed to stabilize the three unstable factors:

  1. 1

    solder amount

  2. 2

    heat supply

  3. 3

    soldering tip shape

by our unique system.
Especially, we stabilize necessary heat amount for soldering and this is our goal for
“standardization of soldering quality.”

The way to Standardization of Soldering Quality

Stabilization Technology of Solder Amount

Stabilization Technology of Solder Amount

If solder Amount is not steady, soldering will be difficult
because the heat to melt solder and the heat to be transferred to parts will be changed.

The “cut and solder” system of the PSU500 has solved it as follows.

Stabilization of Heat Supply

Heat stability and quick thermal recovery of the soldering tip are very important
at soldering consecutively and for the parts which has big heat loss.

The “cut and solder” system of the PSU500 has solved it as follows.

Stable Soldering Tip Technology

Stable Soldering Tip Technology

When soldering with a metal soldering iron tip, the shape of the tip changing by oxidization and solder leaching are not avoidable.

The “cut and solder” system of the PSU500 has solved it as follows.

Benefits Arising from Standardization

Consecutive Stability

Consecutive Stability

The PSU500 is Automated Point Soldering Robot System developed
for standardizing and stabilizing soldering.

Lead-free and Silver-free Solder

The PSU500 can support lead-free and silver-free solder, requiring no nitrogen gas.
There is no problem to use high-melting solder wire
because our PSU500 uses the high-temperature heaters.

7 Advantages of the Cosmic Automated Point Soldering Robot System

  1. The soldering tip uses ceramics, not metal, therefore, long life.
  2. The cut system stabilizes the solder amount and no waste.
  3. The high-power heaters that quickly raise temperature stabilize the heat.
  4. Soldering method has been all digitized.
  5. Almost no solder balls and flux spattering.
  6. Reduces defect rates.
  7. It contributes soldering time to be shorter.
