Solder Pastes Selection Guide: Technical Criteria & Application Standards
Solder Pastes selection guide: technical parameters, mounting and compliance standards, and Soldex, Felder, Hawcon, Feray comparison.
Solder paste is an auxiliary material that dissolves the oxide layer on the metal surface to be soldered, helping molten solder wet and spread over the surface. It is used together with a soldering iron for tinning cable ends, soldering connectors and terminals, preparing copper surfaces for soldering and repair work. In this category, Soldex, Felder and Hawcon solder pastes are available in packages such as 50 g, 100 g and 250 g, along with 10 g solder cream in a syringe. Choose the paste according to the application area recommended by the manufacturer, whether residue cleaning is needed after soldering, and the package quantity suited to your consumption. Solder cream and solder paste must not be confused: solder cream is a mixture that contains solder alloy powder and is used for soldering surface-mount components, whereas solder paste is a flux that prepares the surface for soldering and is used together with solder wire. The Solder Pastes category on Welibaba includes 11 active models from leading manufacturers such as Soldex, Felder, Hawcon, Feray.
Key Technical Parameters for Selecting Solder Pastes
To specify the right Solder Pastes model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Gram | 100 gr, 10gr, 250gr, 50gr | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Soldering Tools and Materials.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Soldering Iron Tips, Heat Transfer Pastes, Pencil Soldering Irons.
