Introduction to Wave Soldering Fixtures

Wave Soldering - DEED-3D

What is Wave Soldering?

Wave soldering is a process in which the welding surface of a plug-in circuit board makes direct contact with high-temperature liquid tin to achieve proper soldering. A special device creates an inclined surface on the liquid tin, forming a wave-like phenomenon, hence the name “wave soldering”. The primary material used in this process is the solder bar.

Lead-free wave soldering requires higher temperatures, making circuit boards more susceptible to bending during the process. Wave soldering fixtures provide maximum protection to circuit boards, preventing bending and ensuring smooth transportation of irregularly shaped boards commonly found in the automotive and consumer electronics industries.

Wave Soldering Fixtures: Principles and Benefits

Wave soldering fixtures protect the bottom components of circuit boards during the soldering process and enable selective soldering when paired with wave soldering devices. Since most fixtures are thick (sometimes up to 15mm), they prevent solder from running onto the board. The oxide layer on the solder surface is also removed by the edge of the fixture before the board reaches the wave, ensuring a clean solder wave when welding begins.
To increase the hardness and withstand high-strength welding, reinforcing bars can be added to the wave soldering fixture. Additionally, fixtures can be equipped with upper heat absorption blocks, component fixtures, and other auxiliary devices. Wave soldering fixtures help standardize product line width, allow for welding different boards on the same line, and enable rapid process changes for different boards using bar code readers and other identification tools.

Application Requirements of Wave Soldering Fixtures

Temperature: Wave soldering furnaces have high temperatures, necessitating the use of high-temperature-resistant materials.
Strength: Wave soldering fixtures must have high strength to ensure that circuit boards do not bend during the process.
Tin Infiltration: The fixture material must not allow tin seepage to prevent excess solder on the circuit board, which could result in product defects.
Recommended MaterialsAntero 800 and ULTEM 1010

Antero 800 and ULTEM 1010 are materials recommended for wave soldering fixtures due to their excellent properties:

High-temperature resistance: Both materials can withstand the high temperatures present in wave soldering furnaces.
High strength: These materials provide the necessary strength to ensure that circuit boards do not bend during the soldering process.
Tin infiltration resistance: Antero 800 and ULTEM 1010 do not allow tin seepage, preventing excess solder on the circuit board and potential product defects.

In conclusion, wave soldering fixtures play a crucial role in protecting circuit boards and ensuring an efficient soldering process. By using high-quality materials like Antero 800 and ULTEM 1010, manufacturers can achieve optimal results during the wave soldering process.
