Matters needing attention in the production and design of shielding cover manufacturers in Dongguan
Dongguan shielding cover manufacturers need to pay attention to the following matters when designing the shielding cover: 1. If the shielding cover needs double-sided reflow soldering, it must ensure that there is a safe bonding wire length (referred to as JPL), based on the pad surface tension of 0.0375g In the case of /mm, the JPL value (mm) should not be less than the shield weight (g) / 0.01875 g/mm. 2. The asymmetric shielding cover that needs to be placed in a specific direction must have polarity marks on the shielding cover and packaging tape; the conveying direction can be clearly identified in the engineering drawing; the packaging tape should be as limited as possible. The positioning holes defined above can be used as polarity marks and need to be represented in the engineering drawings. If you want to know more, please add V:, consult and understand
