What is Lambda wave soldering?
What is Lambda wave soldering?
In the area where the board separates from the wave, the exit zone, the solder does not flow freely but is pushed by the moving board and assumes the travel speed of the board in the conveyor. This allows the solder to drain off without hindrance.
What is selective wave soldering?
Selective soldering is a variant of wave soldering used mainly for soldering printed circuit boards that are assembled partly or even entirely with through-hole components.
What is the difference between reflow and wave soldering?
Wave soldering and reflow soldering are two soldering techniques that are totally different from each other. In wave soldering, the components are soldered, with the help of wave crest, which is formed by a melted solder. Reflow soldering is soldering the components, with the help of reflow, which is formed by hot air.
What is a wave solder pallet?
Selective Wave Soldering Pallets are used to apply TH components to printed circuit boards during PCB assembly. The pallets are made of a glass epoxy insulated material. They protect the SMT components in the circuit and expose the unmasked components to wave soldering.
Is wave soldering still used?
Wave soldering is mainly used in soldering of through hole components. However, there is still significant wave soldering where surface-mount technology (SMT) is not suitable (e.g., large power devices and high pin count connectors), or where simple through-hole technology prevails (certain major appliances).
How do you take a wave soldering profile?
6 – Wave soldering and thermal profiles
- Preheating. The temperature of the board (component side) during preheating should rise as quick as possible to 45 °C (with maximum slope of 2 °C/s) and just before soldering to the temperature of 85 °C.
- Wetting time.
- Dwell time.
- Soldering time.
- Solidification time.
- Cooling time.
How does wave soldering work?
Wave soldering is a bulk soldering process that enables one to manufacture many circuit boards in a very short amount of time. It works by passing each circuit board over a pan of molten solder. A pump in the pan creates a “wave” of solder that washes over the board, soldering the components to the board.
Why wave soldering is the best choice for THM components?
Wave soldering is the preferred method for production soldering because it can be quickly set up, and it will solder a lot of boards in very little time. Wave soldering does have some limitations, however, and not all boards can be run through this process.
What is wave soldering process?
Wave soldering is a large-scale soldering process by which electronic components are soldered to a printed circuit board (PCB) to form an electronic assembly. The name is derived from the use of waves of molten solder to attach metal components to the PCB.
What is a PCB pallet?
PCB pallet 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.

Who invented wave soldering?
In 1947, the transistor was invented by William Shockley, John Bardeen and Walter Brattain at Bell Laboratories in Murray Hill, NJ. This lead to the reduction in the size of electronic components and with later developments in etching and lamination paved the way for a production level wave solder technique.
