Small double wave soldering machine

Wave soldering refers to the molten solder (lead-tin alloy), sprayed by an electric pump or electromagnetic pump into the solder wave required by the design [1], can also be formed by injecting nitrogen into the solder pool, so that it is pre-installed The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
Wave soldering process: insert the component into the corresponding component hole → pre-apply flux → preheat (temperature 90-100°C, length 1-1.2m) → wave solder (220-240°C) cooling → cut off excess plug-in pins → check .
With the enhancement of people's awareness of environmental protection, wave soldering has a new welding process. In the past, tin-lead alloy was used, but lead is a heavy metal that can cause great harm to the human body. As a result, a lead-free process was promoted, using *tin-silver-copper alloy* and special fluxes, and the soldering temperature required a higher preheating temperature.
In most products that do not require miniaturization and high power, the through hole (TH) or mixed technology circuit boards are still used, such as TVs, home audio and video equipment, and digital set-top boxes, etc., and through hole components are still used, so crests are needed. weld. From a process point of view, wave soldering machines can only provide a few adjustments to the most basic equipment operating parameters.

Project

Method of operation

Maintenance amount

Flux spray device

1. The flux is regularly replaced with new flux
2. Cleaning the flux jet box

February/Once
One month/once

Preheater

1. Whether it reaches the indicated temperature

One hour/once

Tin stove

1. Clean the oxide of the nozzle, remove the nozzle, remove the nozzle, and remove the oxide between the layers of the net;
2. After the tin has been used and aged for a long time, it must be replaced completely. First, increase the furnace temperature to more than 260°, then disconnect the power supply, and put the tin out with a stainless steel spoon

Six months/once
Once a year

Transmission part

1.Each transmission part should be kept well lubricated and all lubricated with high temperature grease.
2. The tightness of the transmission chain should be checked and adjusted regularly.

One month/once
One month/once

Electric control system

1. Clean the dust in the electric box
2. Check the electrical appliances in the electric control box and tighten their wiring screws.
3. Regularly check the joints of the electric heating pipes in the preheater and tin furnace.
4. Correction of tin furnace and preheating temperature

One month/once
One month/once
One month/once
Once a year

Whole machine

1. Always keep the body and electric control box clean.
2. Except for the relevant technicians, anyone should not operate the machine casually to avoid operating errors and causing damage.
3. It is strictly forbidden to put the solid solder directly into the tin furnace to melt the tin in the first use.

Precautions:
1. The flux should be a special flux for wave soldering
2. Regular cleaning of tin slag in the furnace
3. Regular cleaning of nozzles
4. Add tin at high temperature in the tin furnace, pay attention to safety when cleaning the tin slag, and beware of burns
5. The height of the track must be higher than the height of the tin furnace to avoid damage to the tin furnace
6. The tin furnace is turned on in advance to melt the tin, and the tin furnace temperature reaches a constant temperature before the plate can be passed.

About delivery
All the equipment of the company includes freight and distribution fees, excluding the cost of going upstairs, depending on the distance, choose logistics consignment or door-to-door delivery
On-site installation and commissioning
The company is responsible for distribution, and there are professional engineers on-site installation, commissioning and training, or guidance and assistance through remote video or telephone
1 year warranty
After-sales promise that all parts of the wave soldering machine are guaranteed for one year, except for problems caused by human factors
Lifetime service
The company's wave soldering provides lifetime maintenance, paid service, and only charges labor and material costs

Preparation before installation and commissioning
1. Door-to-door time: within 2 working days after all the following tasks are ready, special circumstances will be discussed separately
2. Logistics transportation: After receiving the goods, customers who choose logistics transportation should initially place the equipment and prepare all the materials indicated below
3. Door-to-door delivery: Customers who choose door-to-door delivery need to reserve space in advance to prevent equipment and prepare all the materials indicated below
Material preparation:
1. Power connection: lead the power supply line to the device according to the requirements of the device and leave a length of more than 3 meters to connect to the device
2. Air connection: If there is a gas source in the workshop, lead the air pipe to the side of the equipment and leave more than 3 meters long to connect to the equipment. If there is no air source in the workshop, you need to prepare an air compressor in advance and prepare the necessary accessories
3. Tin bars: Prepare enough tin bars in advance according to the tin capacity requirements of the equipment, so that the master can directly melt the tin for on-site trial welding test and training when he comes to the door.
4. Flux: The flux that needs to be used when the product is ready for trial soldering. The test requires a minimum of 2 liters
5. Cleaning agent: used to wash the spray nozzle of the flux, if not temporarily, it will not affect the debugging
