is Prototype pcb manufacturing reliable in 2021?2021-11-19
Output mounting of printed circuit boards
There are two main types of prototype pcb manufacturing mounting – lead-out and surface. Lead-out wiring of printed circuit boards is performed when the ends of the components push through the through holes of the printed circuit board and then soldered.
The holes are prepared in advance in the places of the control point of the installation of the elements, and the fastening takes place from the back side. The leads that protrude through the through holes of the board are wetted by a wave of molten metal – fixation occurs when solidified.
Prototype pcb manufacturing Method fades into the background
Lead-out mounting of Prototype pcb manufacturing is also called through-hole mounting or TNT technology. Now the method fades into the background due to the automation of processes and gives way to surface mounting. But there are still categories of electronic products where elements can be speedy using through holes.
SCOPE OF OUTPUT WIRING
Installation in holes is distinguished by reliability and improved quality of fixation, since the main part carries out manually. Typically, lead-out manufacturing of printed circuit boards is common when it is necessary to manufacture high-power products, as well as in the manufacture of equipment to which special requirements impose.
Prototype pcb manufacturing special requirements These include:
- internal power supplies,
- engines and power complexes of the apparatus,
- automated control systems,
- monitors with high voltage circuits, etc.
Lead-out Prototype pcb manufacturing has an important advantage – improved electrical conductivity. This is especially important for complex and multifunctional instruments. Also, soldering into holes is common in the repair of electrical circuits.
The experience and high qualifications of our employees allow us to quickly fulfill orders for the manufacturing of printed circuit boards with lead-out components. The productivity of soldering points is on average 5,000 pieces per day.
Benefits of Lead out PCB mounting
Most often, output manufacturing of printed circuit boards is common for small-scale production, since such circuits weigh a lot, and the time of the production process increases due to the long before and after manufacturing processing. Nevertheless, there are also undoubted advantages of the technique:
- The risk of damage to components is less – with TNT installation, the boards get heating the oven, so the risk of overheating or the formation of micro-cracks eliminate.
- The possibility of marriage is reduced to zero – most of the processes perform manually by experienced specialists. This allows you to clearly and reliably fix all contacts.
- Small Component Strength and Precision – Push-through mounts use more solder material to extend product life.
- Lead-out Prototype pcb manufacturingis also beneficial in that there are no strict requirements for the components, and the pins can also bond to the inner layers of the panel.
Preparing Components for output Mount
The key point in lead wiring of printed circuit boards is preliminary preparation. The first typical step involves forming and trimming using automatic devices. Preparation has several goals:
- Align and correct the pins, if necessary.
- Provides a certain mounting clearance between the terminals.
- The distance between the components and the Prototype pcb manufacturingis easy to check.
- The elements come on the printed circuit board during manual manufacturing or prior to the soldering stage.
The following are the main stages of output wiring:
- Installation of elements on a dielectric plate manually or automatically.
- Soldering of components with a wave of solder, manual or selective method.
- Also, Blasting or ultrasonic cleaning of the board from solder residues.
To calculate the cost of installing Prototype pcb manufacturing, leave an online application on the website, and the specialists will formulate the exact price within 10 minutes.
Prototype pcb manufacturing cost comes up of several factors:
- The number of soldering points.
- The cost per point depends on the amount of points – the more there are, the more favorable the price.
- Also, Surface or outlet method of installing components.
At the same time, the calculations of the cost of installing Prototype pcb manufacturing in are approximate and may vary depending on the duration and characteristics of the installation.

Today, more and more often, elements have surface mounted on an electronic board, displacing lead-out mounting.
This is due to a few advantages of the SMD method:
- Ability to use the smallest component sizes.
- However, the elements are lighter and lighter.
- There is no need to trim the leads at the end of the solder.
- Also, no hole drilling required in the board.
- Installation is simple and streamlined system.
Surface mounting of Prototype pcb manufacturing. Technological processes are easy to space apart in time. First, solder paste applies to certain places on the printed circuit board, after which the electronic components install and the device subjects to complex soldering.
Prototype pcb manufacturing Surface mount features
Installation of Prototype pcb manufacturing we have its own characteristics that should consider at the preparatory stage. An important point is the quality of the pasta, since it plays a special role during production.
High-quality paste consists of flux, solder powder and stabilizing elements. Solder paste for surface mounting replaces the functions of flux and solder:
- The surface of the board prepares from dirt.
- Moreover, the paste distributes the solder to the pads.
- It is a stabilizer and protects the solder from spreading.
- Also, Fixes elements securely to the board surface.
- Acts as a bonding contact between all components.
All stages are pass out on automatic installers and convection ovens, which are easily familiar to the characteristics of the products and the requirements of the project documentation. This eliminates the need to carry out stages manually and significantly speeds up the production process.
