Dip soldering is a small-scale soldering process by which electronic components are soldered to a printed circuit board (PCB) to form an electronic assembly. The solder wets to the exposed metallic areas of the board (those not protected with solder mask), creating a reliable mechanical and electrical connection.
Dip soldering is used for both through-hole printed circuit assemblies, and surface mount. It is one of the cheapest methods to solder and is extensively used in the small scale industries of developing countries .
Dip soldering is the manual equivalent of automated wave soldering. The apparatus required is just a small tank containing molten solder. PCB with mounted components is dipped manually into the tank when the molten solder sticks to the exposed metallic areas of the board.
Dip soldering is accomplished by submerging parts to be joined into a molten solder bath. Thus, all components surfaces are coated with filler metal. Solders have low surface tension and high wetting capability. There are many types of solders, each used for different applications. Such as Lead-Silver for strength at higher than room temperature. Tin-Lead is used for General Purpose; Tin-Zinc is used for Aluminum; Cadmium-Silver is used for strength at high temperatures; Zinc-Aluminum is used for Aluminum and corrosion resistance; Tin-Silver and Tin-Bismuth is used for Electronics. Because of the toxicity of lead, lead-free solders are being developed and more widely used. The molten bath can be any suitable filler metal, but the selection is usually confined to the lower melting point elements. The most common dip soldering operations use zinc-aluminum and tin-lead solders.
There is not much equipment or setup for this process, all that is needed is the solder pot with its temperature control panel, the bath of molten solder, and the work holding device. Usually the work holding device is custom made for each respective workpiece for either manual or automated dipping.
Some materials are easier to solder than others. Copper, silver, and gold are easy to solder. Iron and Nickel are a little more difficult. Titanium, magnesium, cast irons, steels, ceramics, and graphites are hard to solder. However, if they are first plated they are more easily soldered. An example of this is tin-plating, in which a steel is sheet coated with tin so that it can be soldered more easily.
Dip Soldering is used extensively in the electronics industry. However, they have a limited service use at elevated temperatures because of the low melting point of the filler metals. Soldered materials do not have much strength and are therefore not used for load-bearing.
Four Tips to Selecting a Small-run PCB Assembly Manufacturer
Working with low-volume PCB assemblies has its benefits and cons. As the purchaser, there are several pointers that can help you get the most from your assembly. In this article, we will explain how to make use of the good things and ways to go around the down sides.
Easy methods to Pick out a Small-run PCB Assembly Manufacturer?
The information referred to here should help you maximum benefit out of your low-volume PCB assembly order.
1. Only One Service Provider
Find a low-volume PCB manufacturer who could be a one-stop supplier for all your PCB needs. The main advantage of working with a small order is you don’t have to coordinate with several organizations or individuals. Your order can be treated by a single point of contact.
2. Importance of Prototypes
Even when working with small orders, you must insist on use of prototypes – though it comes at an added expenditure. Prototypes will enable you to inspect your design and enhance it, as needed.
3. Small-run PCB Manufacturer
Fabricating low-volume PCB assemblies can be quite a task when using the services of an unsophisticated manufacturer. Because the order quantity is low, expense of production will probably be gently higher. Therefore, any mistake from the PCB manufacturer will contribute to higher losses for the client.
4. Standard PCB Practices
Standard tips related to PCB production ought to be adopted even if working with a low-volume PCB assembly. This can include design, fabricating, assemblage, and in addition PCBA testing procedures.
Working with a low-volume PCB assembly has its own range of positive factors. With the help of standard guidelines allows you to build an order that might help you in the long term.
