Common Types Of Wave Soldering Fixtures

Several common wave soldering fixtures and their respective characteristics of what?

Wave soldering fixtures, also known as the over-tin oven wave soldering fixtures, is designed for some of the parts on the PCB need to protect the fixtures, or through the fixtures to play a role in assisting the positioning of the plug-in production of wave soldering fixtures of a variety of materials today, let us let us talk about several common wave soldering fixtures and their characteristics.

The glass fiber plate wave soldering jig:

Wave soldering fixtures made of glass fiber plate good flatness, smooth surface, no pockmarks, high mechanical properties and dielectric properties, heat and moisture resistance, good processing performance. At room temperature 150 ℃, still has high mechanical strength, can withstand high temperatures up to 300 degrees above in the dry state,, wet state of good electrical properties, flame retardant, used for electrical, electronic and other industries in the insulating structural components are black, white, green, yellow, etc., there are also anti-static fiberglass panels are available at a low price. Disadvantages: easy to delamination after a long time, not resistant to strong acids and alkalis, lead-free solder is not suitable, the service life is also relatively short.

The wave soldering jig of synthetic stone plate:

1. The product has high elasticity plasticity and impact resistance.

2. Because it is a stone synthesized from natural silica and polymer resin, is acid-resistant material.

3. The color will not fade for a long time.

4. Low temperature conductivity ensures heat distribution on the substrate.

5. It can maintain dimensional stability and flatness after long-term use.

6. The Synthetic Resin component of artificial stone can effectively block the activity of flux and prevent the generation of tin tip.

7. Temperature resistance is generally between 300-350 degrees, and for a short period of time, the temperature resistance can reach 385 degrees. Artificial stone is the ideal material for the base plate of the furnace fixture but there are many types of synthetic stone on the market, there are domestic and imported, the nature of the difference is large, the selection of materials more difficult.

Titanium alloy wave soldering jig:

Titanium alloy manufacturing wave soldering strength and fracture toughness is high, strength and ordinary carbon steel is similar, fatigue strength and crack extension resistance performance is good, good low-temperature toughness, excellent corrosion resistance titanium alloy melting point of 1660 ° C, higher than the melting point of iron, has a high thermal strength of certain titanium alloys, the highest working temperature of 5500 C, is expected to reach 700 C. Corrosion resistance is good: 550 ° C or below is easy to be in the titanium alloy The surface of the titanium alloy is easy to form a dense oxide film, so it is not easy to be further oxidized. Titanium alloys have the advantages of high strength, high temperature resistance and corrosion resistance, but relatively expensive.
