At present, our company through a large number of experiments, choose different types of ink and viscosity, adjust the pressure of screen printing, basically solve the hole hole and uneven, has adopted this process for mass production.
The domestic leading automobile board represented by Shanghai Electric Company has actively participated in international cooperation and introduced advanced technology. The high-frequency PCB used for millimeter wave radar has been mass-produced.
In particular, it should be noted that the bypass capacitor needs to pass through two holes when connecting the power layer to the formation, so that the parasitic inductance of the hole will be multiplied.
PCB Assembly, PCB Manufacturing and prototyping The technology used in PCB production has been greatly modified in order to maintain quality and durability with zero defect mass production.
Тогда при каких обстоятельствах производственные материалы SMT повлияют на качество сварки печатных плат?Каково содержание проверки технологичности печатных плат (DFM) для обработки исправлений SMT? Чтобы узнать больше, посетите официальный сайт Kingford.
Обработка печатных плат — это многопроцессный процесс, каждое звено производства тесно связано, любая проблема на любом звене приведет к плохой сварке печатной платы, в этом статье описано, что как завод SMT гарантирует качество обработки печатных плат.
Compared with the dip welding process, the motion of solder solution and PCB board in the drag welding process makes the thermal conversion efficiency better than that in the dip welding process.
The size of the welding nozzle should be as large as possible to ensure the stability of the welding process and not affect the adjacent components on the PCB, which is important to the design engineer, but also difficult, because the stability of the pro
The grounding isolation belt near the crystal oscillator must be well grounded. In a word: the copper coating on PCB, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line back...
PCB is the mother of electronic products. As long as the electronics industry continues to develop, there will always be business opportunities, and if it can survive the trough, it will meet the peak.
it is generally sufficient to handle high end harmonics and keep the transient signal low enough, that is, common-mode EMI can be dropped very low. The PCB layer-stack design example presented in this paper will assume layer spacing of 3 to 6mil.
One end of the triangle is connected to a signal wire and the other is connected to ground. When static electricity is present, a tip discharge is generated which consumes electrical energy.
