Preform

Electroloy's solder preforms are used in a wide range of industries such as computer, automotive, semi-conductors, consumer electronics, components manufacturing as well as telecommunications.

Electroloy offers a variety of solder preforms that comes in many shapes & sizes to suit many applications that requires precise amount of solder. Our preforms come in standard shapes like rectangles, squares, discs, washers and pellets. In addition we also customize preform of special shapes & alloys for difficult applications.

Electroloy preforms are extruded, rolled, stamped or compacted to meet up with high tolerances to ensure volume accuracy as well as meet up with customer specifications. So call Electroloy for more details. [ Enquiry ]

Solder Refills:

Our solder refills are available in tape and reel packaging for easy use in high volume and automated manufacturing processes. They can be dispense through pick and place equipment in SMT line. These are available in standard 7" and 13" IEC reels.

Benefits:

  • Fast placement using standard equipment
  • Suitable for increasing the solder volume in a solder joint.
  • Reduces additional process to achieve desired results.
  • Compatible to all standard alloys in solder paste.
