A few years ago, a colleague contacted me with a question: "How can we weld a plate with a Tg of 180°C or even 200°C at 225-245°C without damaging the plate? Even with lead boards, the peak reflux temperature is much higher than the Tg of the boards....
Our results for the first quarter of 2021 reflect our strong underwriting capabilities and focus on relationship banking. We are well positioned to capitalize on this successful momentum as the economy continues to reopen and look forward to the rest of t
Therefore, for the first piece inspection, it is necessary to look at the following aspects: Measure and record all properties of the board, whether it is size or resistance. Once these values have been verified by the design specification, you can rest a
What types of consumer electronics are PCB boards suitable forBasically, all electronic products need to use PCB boards, but not every electrical appliance needs a circuit board, simple electrical appliances may not need a circuit, such as a motor. So, wh
