PCB clamps PCB lockers for solder pallets

HONY®PCB Wave Solder Pallet this material is a fiber-reinforced plastic for mechanical and electrical applications. With good performance against electric arc and tracking, it is an ideal material for solder paste printing, SMT process, reflow soldering and wave soldering.It can keep its physical properties at increasing high temperatures. So it can reach high precision without any deformation. There are no layering, bubbles, deformation when working at 380 ° C for a short time. Function: The wave soldering tray is a tooling fixture for carrying and protecting PCB and its components. In addition to the traditional functions of preventing PCB deformation, auxiliary support and positioning, it also improves the process, protects components, improves quality, and improves The function of production efficiency. Generally, the tray is composed of several elements shown in Figure .

Jig material: In order to maximize the service life of the pallet, the material of the pallet must be able to withstand high temperature and harsh process conditions, especially to meet the requirements of lead-free soldering. The main material generally has the characteristics of high dimensional stability, good thermal shock resistance, flatness after repeated use, corrosion resistance (flux and cleaning agent) and non-moisture absorption. Commonly used materials are durostone, epoxy resin board, bakelite etc. For the lead-free assembly and welding of electronic products, durostone and epoxy resin board FR4 are usually used due to the need for high-temperature welding. Very few use bakelite materials. Durostone is a specially treated glass fiber compound, which is a subsidiary product of petroleum. It has the characteristics of high heat resistance, no deformation, and difficult processing, but the processing accuracy is high, and the price is relatively high. Generally, it can be repeated 1-2 million times without problems, and it is suitable for mass production. The epoxy resin board FR4, relatively synthetic stone, is easier to deform, has no electrostatic protection, but is better processed, has sufficient heat resistance, and is well designed. It can also be passed nearly 10,000 times, but the price is relatively low. It is also suitable for mass production, so it is more cost-effective. It is recommended for the electronic product assembly industry.

Use classification: It can be divided into two main categories, one is the solder mask pallet, which aims to improve the quality of the manufacturing process. It is used for wave soldering surface using solder paste reflow process to protect the chip components during wave soldering and avoid the secondary melting of solder joints; the other is the jigsaw pallet, which is used to improve production efficiency. It is used for similar jigsaw or Different PCBs undergo wave soldering at the same time, and the other is auxiliary trays, which are aimed at other assembly process requirements. It is used for auxiliary positioning of on-board components and irregular PCB through-board welding. See main products various purposes.

All kinds of wave soldering trays all have the effect of alleviating the thermal deformation of the PCB, and there are no special requirements on the process side of the PCBTOP surface, which saves the cost of PCB materials. If required by the process, the wave soldering universal integrated pallet that combines the three functions and purposes into perfect.

Process flow: SMT semi-finished products → inspection → loading trays with hand-inserted through-hole parts → wave soldering → picking up the board and returning the tray → handling tin → assembly → functional inspection test → component board packaging. After SMT/AI completes the PCBA semi-finished product in the manufacturing process, in the hand-inserted device mounting process, the jig residue and other foreign objects must be inspected and cleaned before the insert and wave soldering can be implemented.

-Eliminate solder skipping and reduces rework

-Allow processing of odd-shaped PCB's through conveyor system

-Increase assembly production by eliminating hand gluing and masking operations

-Assure easy,safe,cost-effective handling of PCB

What are the most important things to pay attention to while using solder pallet fixture?

1. Gentle care and proper handling. Fracture damage most often occurs while transferring the unit. To avoid damage to the protective wall, as well as other parts of the solder pallet fixture, it is important to have a dedicated management position.

2. Store the solder pallet fixtures in an upright position. Deformations can be happened if the unit is improperly stored. To avoid deformations caused by stacking it is recommended that units be stored on shelves.

3. Avoid strong acid and alkali contact. Exposure to strong acids or bases will easily corrode the solder pallet fixture. To avoid this a neutral flush is recommended.

4. Avoid using alcohol and alcohol-based cleaning agents. Saponifiers are the recommended cleaning agent.

5. Shockproof transportation. Units can receive shock damage while being transported through the A shockproof cart is recommended.
