SOLDERING PASTE MECHANIC V4B45 138C 40g
Description
Mechanic V4B45 Solder Paste Sn42/Bi58 (138°C) – 40g
Looking for a reliable solution for safe soldering of delicate components?
The Mechanic V4B45 low-temperature solder paste (liquid tin) is a professional-grade product designed for advanced consumer electronics repair shops. Thanks to its specialized low-melting-point alloy, this paste allows you to work on components where traditional lead-free solder could cause overheating and permanent damage to the PCB or neighboring chips.

Key Features:
- Low Melting Point (138°C): Drastically reduces the risk of thermal damage to delicate components (e.g., FPC connectors, USB ports, BGA chips).
- Ideal for Multi-Layer Boards (Sandwich): Indispensable for modern smartphone repairs (e.g., iPhone, Samsung) where precise bonding and separation of motherboard layers is required.
- Lead-Free Alloy: The Sn42/Bi58 composition (42% Tin, 58% Bismuth) ensures compliance with environmental standards while maintaining excellent wetting properties.
- Easy Application: Packaged in a practical 10cc syringe/tube (approx. 40g net weight), which—when combined with a dispensing needle—ensures maximum dosing precision.
- Type 3 Particle Size (25-45 µm): The optimal grain size guarantees even distribution on BGA stencils without clogging the apertures.
Applications:
- BGA reballing in smartphones, tablets, and laptops.
- Soldering SMD components sensitive to high temperatures.
- Mounting plastic-molded parts (charging ports, headphone jacks) that easily melt with standard solder.
- Servicing multi-layer (sandwich) motherboards.
