Wave soldering pallet 2

Use of PCB Pallets in Wave Soldering

Use of PCB Pallets in  Wave Soldering
Patch components are used more and more on the circuit board, but there are still some perforated components between them. For this kind of board, selective soldering is the best solution, but not every company has enough funds to purchase selective soldering equipment, or the number of this type of circuit board is too small, specifically to buy selective soldering equipment is not Cost-effective. Manual welding is prohibited in certain industries such as the automotive industry

Therefore, in PCB wave soldering, using trays to block those patch components is a good method: reliable, fast production, and adaptability to high-capacity requirements.

Wave soldering pallet 2

The benefits of using trays:
Lead-free soldering requires higher soldering temperatures. Therefore, the circuit board is more easily bent during welding. The tray provides maximum protection of the circuit board during soldering and prevents bending.

Similarly, in the automotive and consumer electronics industries, many special-shaped circuit boards have emerged for the needs of applications. It is sometimes difficult to transport these shaped plates with conventional chain rails and mesh belts, and placing the circuit board plates in trays allows any type of circuit board to be shipped.

Wave soldering pallet 1

By soldering some of the bottom components through the tray, it is also possible to use PCB wave soldering equipment for selective soldering of the product.

Since most trays are thick (sometimes 15 mm), solder certainly does not flow to the top of the board. The oxide layer on the solder surface will also be washed away by the edge of the tray before the board reaches the peak, so that when the solder starts, the tin is relatively clean.Wave soldering pallet 6

By adding some stiffening strips to the tray, it can increase its hardness to withstand high-strength welding. It is also possible to install heat-absorbing blocks, component fixing devices and some other auxiliary devices on the upper part.

The use of pallets also helps standardize the width of the product line, soldering different circuit boards on the same production line, and can use bar code readers and other identification tools to quickly change process programs for different boards.

Although there are many advantages to using trays in lead-free soldering, it can also cause solder balls.

Requirements for pallet materials:
In order to maximize the service life of the trays, the trays must be made of materials that can withstand high temperatures and harsh process conditions, especially for lead-free soldering.

Wave soldering  tray 1

To meet these requirements, the material used to make the tray must meet the following characteristics:
• High dimensional stability
• Good thermal shock resistance
• Can remain flat after repeated use
• Corrosion resistance (flux and cleaning agent)
• Does not absorb moisture

The use of the tray brings the process problems:
The flux system must be able to spray the circuit board completely with flux. Poor tray designs can lead to “shadow effects” in flux spraying: Some parts of the board have insufficient flux or no flux at all. The flux must be sprayed onto the board and spread through the capillary action.

Before the tray touches the crest, it must be heated in the preheating unit. A typical preheating configuration is a combination of heat pipes and hot air forced convection. If the temperature drops before contact with the peak, the tray will have an endothermic effect, making the welding process difficult to control.

The use of trays requires a wave height of up to 0.5 inches (12.5 mm). In the case of such a high pump speed, the use of nitrogen can help reduce dross. When using pallets in lead-free soldering, Vitronics Soltec’s perturbed “smart wave” can also promote tinning of the perforated component.

In addition, we must pay special attention to keeping the circuit board in the pallet flat. If there is a gap between the circuit board and the tray, the flux will flow into the gap, and the solder will flow to the board when passing through the peak. This will cause solder residue on the board.

Wave soldering  tray 3

The gap between the circuit board and the tray may cause solder residue on the circuit board

Circuit board and tray design recommendations:
Avoid placing larger components near the piercing element as this can cause shadowing effects and tin difficulties.

Leave proper clearance around the pins and edges of the through-hole components so that solder can flow. These tin guides will guide the solder to the seat of the tray opening, while also greatly improving the solder flowability.

www.smthelp.com

Wave soldering  tray 4

The tin slot at the tail of the tray allows the solder to flow smoothly back to the tin tank

The opening of the tray should be as large as possible to facilitate the flow of solder. This will reduce some of the welding defects, such as: short circuit and solder balls. At the same time, it is also beneficial to the solder filling of the through hole, because the large opening also means that there is more energy to enter the welding area.

Surface Mount Assembly Classifications for EMS

Surface Mount Assembly Classifications

Three general classes for the intended end use of electronic assemblies have been established. As applications and functionality increase there may be overlap of equipment between classes. The owner of the application has the responsibility to determine the class that applies. Although a single class may be referenced, specific requirements defined in other classes may apply as well. If a class is not stated for a criterion then the single criterion applies to all classes.

Class 1: Consumer Products: This class of product includes non-critical applications which shall be reliable and cost effective but for which extended life is not the primary objective. Examples include products manufactured for general consumer applications.

Class 2 – General Industrial. This class includes high performance commercial and industrial products in which extended life if required but for which uninterrupted service is not critical. Application and environmental considerations should be taken into account.

Class 3 – High Reliability. Equipment in this class includes those equipment which continued performance is critical, equipment whose downtime cannot be tolerated, or equipment used as a life support item. Unless otherwise specified, Class 3 shall be used for soldering requirements on military electronic equipment.

Printed circuit assemblies are manufactured in a variety of ways, exclusively using smt devices or smt mixed with through-hole components. Boards which have both SMC’s and through-hole components are called mixed technology boards. Surface

mount components are conventionally attached to the substrate using the reflow or the wave soldering process. Typically PCBs are assembled in one of the following ways and categorized as:

Type 1:

SMC’s only are placed on one or both sides of a printed circuit board. The components are attached via the Reflow soldering process.

Type 2:

A combination of both surface mount and insertion mounted components on a printed circuit board. Both SMC’s and IMC’s are assembled on the top side of the board while SMC’s only are attached to the bottom of the board. Top side smt components are Reflow soldered, while the through hole and bottom side smt components are Wave soldered.

Type 3:

IMC’s are assembled on the top side of the board while SMC’s only are attached to the bottom of the board. The components are soldered in place via the Wave solder process.

The fast growth of these applications and advanced packages has led to the development of high density boards. As the industry increases the use of these boards and packages in its products, two of the greatest challenges that it will face are; establishing effective printing guidelines and utilizing equipment that can reliably produce a wide variety of assemblies.

A company’s success or failure in the surface mount industry will weigh heavily on its ability to adapt to automated manufacturing practices through innovative product design and development. Manufacturers can effectively compete in the electronics marketplace today only by utilizing automated equipment throughout the entire SMC assembly process. This includes addressing changes in the SMC production process from initial board printing to final inspection. The companies that do not act positively on these factors and successfully adapt to changing trends in the electronics market will find their business being lost to competitors and foreign ventures.
