This is achieved by soldering the shielding layer to a solid ground plane... the wires, the construction seams, and the gaps between the shielding cans... using through-hole solder tails to manually solder on the PCB and then solder it To the PCB. The shielding is below 100 MHz, and the tinned copper is preferably above 200 MHz.
Heat the oxidized soldering iron tip to 350°C, then tin-plate the soldering iron tip, clean the FS-100 solder paste with...or HAKKO 599B cleaning wire, and check whether the surface of the soldering iron tip is wet. ...After finishing the soldering work, apply enough solder to the soldering tip. Engineering discipline: automotive. aviation. design. electronic product.
With the rise of consumer electronics, lead-based solders are used... Alternatives to lead are steel, tungsten nickel nickel iron, bismuth tin and tungsten polymers. In an environment where lead-based solder is used for soldering. ...Pre-transistor/IC aging due to transistor-based point-to-point wiring.
