Understanding wave soldering in PCB Assembly

Wave soldering is a bulk soldering process used primarily for assembling PCBs with through-hole components. In this method, the bottom side of a populated PCB is passed over a wave of molten solder. The solder adheres to exposed metal areas, forming secure and conductive joints between component leads and pads.This process gets its name from the "wave" of solder created in the solder bath, which ensures even and consistent soldering across the entire board.

Flux Application A flux is applied to the underside of the PCB to clean the surfaces, remove oxidation, and improve solder adhesion.
Preheating The board is then preheated to activate the flux and reduce thermal shock when it contacts the molten solder.
Solder Wave ContactThe PCB passes over a tank of molten solder where a pump creates a standing wave. As the board glides across, the solder adheres to exposed pads and component leads.
Cooling After soldering, the PCB is cooled in a controlled manner to solidify the solder joints and prevent defects.

Despite the rise of SMT, wave soldering plays a vital role in many applications, especially in:

Power electronics
Automotive electronics
Industrial control systems
High-reliability products with large or odd-shaped components

It is ideal for high-volume production where speed, consistency, and strong mechanical bonds are critical.Advantages of Wave Soldering

Efficient for large volumes

Perfect for batch production with consistent output.

Cost-effective for through-hole components

Faster and cheaper than manual soldering, especially in bulk.

Reliable joints

Delivers durable and uniform solder connections ideal for heavy-duty applications.

Works well with mixed-technology boards

Can be combined with SMT when needed for hybrid assemblies.

Not suitable for fine-pitch or ultra-small components

That’s where reflow soldering excels.

Design constraints

Boards must be designed with wave soldering in mind to avoid issues like solder bridging.

Thermal stress

Improper temperature control can damage components or the PCB itself.

Sophie Belmore 2022-09-13

If you disassemble several electronic devices, you will discover a printed circuit board (PCB), a small green board with identifying marks that resemble a maze. Even though printed circuit boards (PCBs) serve as the basis for almost all electrical circuits in use today, they are usually neglected. The copper on bare printed circuit boards is typically covered with a very thin layer of photo-resist in the industry standard procedure. They have two branch factories that are solely devoted to the design and production of PCBs, PCB Assembly manufacturing, component procurement services, and final product assembly at a decent cost. Their team has over 15 years of expertise in the electronics design and manufacturing industry sectors, spanning everything from PCB design counseling to the material discussion, and components matching to the full turn-key gathering.

Three parameters that affect the cost of PCB board design

aaronking 2021-04-30

Spacing between wiresIn terms of the processing capacity of the PCB manufacturer, the minimum spacing between wires should not be less than 3mil.

From a production point of view, the bigger the better if possible, the more common is 10mil.2.

The aperture tolerance is slightly different depending on the plate, generally it can be controlled within 0.05mm, and the minimum pad width should not be less than 0.2mm.If it is a large area of copper, it usually needs to be retracted from the edge of the board, generally set to 20mil.

In the PCB design and manufacturing industry, under normal circumstances, due to the mechanical considerations of the finished circuit board, or to avoid curling or electrical short-circuiting due to the exposed copper skin on the edge of the board, engineers often spread copper on a large area The block is shrunk by 20 mils relative to the edge of the board instead of spreading the copper to the edge of the board.There are many ways to deal with this kind of copper shrinkage, such as drawing a keepout layer on the edge of the board, and then setting the distance between the copper paving and the keepout.

Here is a simple method to set different safety distances for copper paving objects.

For example, the safety distance of the whole board is set to 10mil, and the copper paving is set to 20mil, and the effect of 20mil shrinkage of the board edge can be achieved.

Application of PCB in the automotive industry

Fanklan Steven 2021-03-01

Factors of increasing the value of automotive PCBIn recent years, the trend of automobile electrification and electronics has become more and more obvious.

As the backbone of electronic products, the importance of PCB manufacturing in the automotive supply chain is also increasing day by day.

Compared with traditional fuel vehicles, the addition of charging, energy storage, power distribution and voltage conversion equipment for new energy vehicles will bring a large number of new application scenarios to PCBs.At the same time, although autonomous driving above L4 cannot be mass-produced in a short time, the gradual penetration of a variety of intelligent driving components will bring rapid development opportunities for the application of high-end high-frequency PCBs in automobiles.According to calculations by relevant departments, only in the powertrain and transmission fields, the value of PCBs on electric vehicles is as high as about RMB 800 per bicycle, which is 20 times the value of PCBs in this field of traditional vehicles.The new demand for electric vehicles mainly comes from powertrain related equipment-on-board chargers, battery management systems (BMS), voltage conversion systems (DC-DC, inverters, etc.)

and other high-voltage and low-voltage devices.Factors of increasing automotive PCB productionA large number of high-voltage and high-power devices contained in new energy vehicles, such as IGBTs and MOSFETs, have high requirements for heat dissipation, which makes the layout of PCBs not too dense, which further increases the amount of PCBs for new energy vehicles.On each new energy vehicle, the total PCB board required for the above-mentioned equipment alone amounts to about 0.8 square meters.However, the total PCB required for a medium-level electronic fuel vehicle is only about 0.43 square meters.

In the internal combustion engine and traditional system of traditional fuel vehicles, the amount of PCB used is very small, only about 0.04 square meters in total, which has greatly increased the output of automotive PCB.According to calculations by relevant departments, the PCB consumption of new energy vehicles equipped with millimeter-wave radar and large central control screens will reach 1.24 square meters, worth 1281 yuan, which is 3.6 times that of traditional fuel vehicles without the above configuration.Factors contributing to the considerable growth rate of China's pcb marketThe production and sales of China's new energy passenger vehicles will continue to grow rapidly in the next few years, and the CAGR is expected to be around 40% in 2018-2025.

The domestic new energy passenger vehicle sales exceeded 1 million in 2018, and it is expected to exceed 2.5 million by 2020, and close to 12 million by 2025, with a market share of more than 40%.Major domestic PCB manufacturers have a relatively complete layout in the fields of automotive infotainment, lighting, powertrain and chassis (steering and braking).It is estimated that by 2025, the global automotive PCB market will reach 58.3 billion yuan, and China is expected to reach 40 billion yuan.
