Why add test points to the circuit board design?
The circuit board design and test points are not used in the production of PCB boards, but after the PCBA is completed, ICT tests are performed to test whether the circuit board soldering has problems and whether the performance meets the requirements. The circuit board also needs to be tested du

Precautions for circuit board soldering
The principle of soldering is a process in which a solid solder wire is heated and melted by a heated soldering iron, and then flows into the metal to be soldered with the help of flux, and forms a firm solder joint after cooling. When the solder is a tin-lead alloy and the soldering surface is copper, the solder first wets the soldering surface. With the wetting phenomenon, the solder gradually diffuses into the metal copper, forming an adhesion layer on the contact surface of the solder and the metal copper, so that both Combine firmly.

How to prevent the warpage and deformation of the board in the production of PCB printed circuit boards
Why is the circuit board required to be very flat on the automated assembly line, if the printed board is not flat, it will cause inaccurate positioning, components can not be inserted into the holes of the board and the surface mounting pads, and even the automatic insertion machine will be damaged . The board with the components is bent after welding, and the component feet are difficult to cut flat and uniform. The board cannot be installed on the chassis or the socket inside the machine, so the assembly plant is also very upset when the board is warped. At present, printed boards have entered the period of appearance devices and chip devices, and assembly plants must have stricter and stricter requirements for board warping.

Quality inspection of prepreg PP for circuit board
The prepreg is a sheet material. The resin is in the B-stage, under the action of temperature and pressure, it has fluidity and can quickly cure and complete the bonding process, and forms an insulating layer together with the carrier. Commonly known as prepreg or bonding film. In order to ensure the high reliability and quality stability of the multilayer printed circuit board, the quality of the semi-solid film characteristics must be tested (trial lamination method). The characteristics of the circuit board electroplating prepreg include the characteristics before lamination and the characteristics after lamination. The characteristics before lamination mainly refer to: resin content%, fluidity%, volatile content% and gel time (S). The characteristics after lamination refer to: electrical properties, thermal shock properties and flammability.

Why do PCB board making holes need to be plugged?
Why do PCB board making holes need to be plugged? Conductive holes are also known as via holes. In order to meet customer requirements, the circuit board via holes must be plugged. After a lot of practice, the traditional aluminum plug hole process is changed, and the circuit board surface solder mask and plug hole are completed with white mesh. Stable production and reliable quality.
