The space between copper planes can act as waveguides for RF frequencies. It makes trace impedance changes and signal losses.
To cut such waveguide effect, put vias, which is essentially a copper cylinder.
When the distances between vias are small enough compared to the wavelength, the board is like continuous copper material, instead of waveguide.

Some online tutorials about soldering TH components, like transistors and ICs, are delicate components and can be easily damaged by heat. When it comes to soldering surface mount IC and components, some prefer to use a reflow oven which heats up the them to a temperature above the melting point of solder. So why?
Wat zou voor een ervaren persoon de gemiddelde snelheid zijn van het assembleren van componenten voor opbouwmontage op een PCB?? Ervan uitgaande dat ze een bureau hebben dat correct is ingesteld (pick and place station) and the PCB has solder paste already applied.
We would like to do wave soldering for the through hole components. All through hole components are top side of PCB. Only test points, which require mask during process, are on the bottom side. So there is a extra labour cost at adding and removing the mask. Can we do wave solder the through hole parts without masking it?
