What is double sided pcb ?

The double-layer PCB board with copper on both sides and metallized holes is being called double-layer board. The circuit board on both sides is covered with circuit boards. However, if the wires on both sides want to be used, the appropriate circuit connection between the two sides should be first provided.  Today the double sided printed circuit board technology remains the workhorse of the assembly industry.  There are near limitless applications for old and new designs.

Applications of double sided pcb board

  • Industrial controls
  • Power supplies
  • Consumer Electronics
  • LED lighting
  • Automotive
  • Phone systems
  • Control relays
  • Hard drives

Single vs double sided pcb

The difference between a double-sided PCB board and a single-sided PCB board is that the single-sided PCB circuit is only on one side of the PCB board, while the double-sided PCB circuit can be distributed on both sides of the PCB board. Wiring of the double sided pcb board are being connected.

In addition to the different production process between double-sided PCB board and single-sided PCB board, there is an additional copper sinking process, which is the process of conducting double-sided circuits.

Advantages of double sided pcb

  • Double sided pcb make it relatively easy to add conductive paths on the board, which means you will have a PCB that better suits your needs;
  • Since both sides of double-sided pcb board are conductive, a large number of ICs and components can be assembled at any time;
  • If necessary, the size of the circuit board can be reduced, because double-sided can be used, this type of PCB may save you money because you may only need to use one board;
  • Double-sided PCB can be used in many different applications and electronic products, double-sided PCB is ideal for demanding applications and advanced electronic products.

Disadvantages of double sided pcb

  • When conducting large currents, double-sided printed circuit boards are not ideal because the copper wires are heated. We are aware of this and ensure that all PCBs are of high quality and are not damaged.
  • When soldering double sided PCB, there is a risk of overheating. However, our PCB experts have manufactured thousand kinds of PCBs and know how to minimize risks.
  • Double sided pcb boards can be very complex, which means they can be difficult to manufacture. The good news is that Hitech has extensive experience in manufacturing various double-sided PCBs. You can count on us to get the job done.

How to solder double sided pcb

In order to ensure reliable electrical conduction of the double-sided printed circuit board, the connection holes on the double-sided pcb board (that is, the through-hole part of the metallization process) should be welded first with wires or the like, and the protruding part of the connecting wire tip should be cut to avoid stabs Injury to the operator’s hand, this is the preparation work for the wiring of the board.

The essentials of double-sided circuit board soldering:

  1. For devices that require shaping, they should be processed according to the requirements of the process drawings; that is, they must be shaped first and then plug-in.
  2. After shaping, the model side of the diode should face up, and there should be no discrepancies in the length of the two pins.
  3. When inserting devices with polarity requirements, pay attention to their polarity not to be reversed. Roll integrated block components, after inserting, no matter it is a vertical or horizontal device, there must be no obvious tilt.
  4. The power of the soldering iron used for soldering is between 25~40 wattages. The temperature of the soldering iron tip should be controlled at about 242℃. If the temperature is too high, the tip is easy to “die”, and the solder cannot be melted if the temperature is low. The soldering time should be controlled at 3~4 seconds.
  5. During the formal welding, generally operate according to the welding principle of the device from short to high and from the inside to outer. The welding time should be mastered. If the time is too long, the device will be burnt, and the copper line on the copper clad board will also be burnt.
  6. Because it is double-sided welding, a process frame or the like for placing the circuit board should also be made, so as not to squeeze the components underneath.
  7. After the circuit board welding is completed, a comprehensive check-in check should be ca
