The 900M Series Pure Copper Soldering Iron Tip Set (5-Pack) is a premium selection of high-conductivity tips designed for precision electronics repair. At Electrapac, we recommend this bare copper set for technicians and hobbyists who prioritize rapid heat transfer and superior tinning capability for delicate soldering tasks.

Product Overview

This set features five essential tip shapes (I, B, K, 2.4D, 3C) crafted from solid pure copper. Unlike standard iron-plated tips, these "inside-hot" bare copper heads offer significantly faster thermal recovery, making them ideal for lead-free soldering and high-density PCB work. They are a perfect fit for popular soldering stations like the Koocu V900, V501, V900C and the XCY 908.

The 5-Piece Essential Tip Guide

• Type I (Pointed): Ultra-fine needle tip for micro-soldering, SMD components, and jumper wires in tight spaces.

• Type B (All-round): A versatile conical tip suitable for general-purpose soldering from any angle.

• Type K (Knife): A blade-shaped tip perfect for drag soldering, clearing bridges, and desoldering multi-pin ICs.

• Type 2.4D (Chisel): Provides a flat surface for better heat contact on larger pads and through-hole components.

• Type 3C (Beveled): A hoof-shaped tip with a concave end that holds a "reservoir" of solder, ideal for high-speed drag soldering of SMD chips.

Key Features for Electrapac Customers

• Pure Copper Core: Offers the highest thermal conductivity available, ensuring the tip reaches the set temperature almost instantly.

• Bare Finish: Because these are not iron-plated, they absorb tin exceptionally well, reducing the risk of "dry" joints.

• Internal Heating Design: Optimized for "Inside Hot" heating elements, reducing heat loss between the element and the workpiece.

• Broad Compatibility: Specifically tested for Koocu and XCY series irons, as well as any standard 936-style soldering station.

• Precision Machining: Each tip is precisely sized (6mm OD / 4mm ID) to ensure a snug fit on the heating element, preventing wobbling during use.

Maintenance & Care Tips

Pro-Tip: Because these are pure copper tips, they require more care than plated tips. To prevent oxidation, always keep the tip "tinned" (covered in a layer of solder) when not in use. Use a brass wire cleaner instead of a wet sponge to maintain the copper surface without causing rapid temperature shocks.

Primary Applications

• Mobile Phone Repair: Using the Type I tip for delicate logic board jumpering.

• SMD Soldering: Utilizing the Type K and 3C tips for fast IC installation.

• General PCB Assembly: The B and 2.4D tips are perfect for resistors, capacitors, and headers.

• DIY Electronics: A must-have set for any hobbyist bench at Electrapac.
