In through-hole assembly, the component leads are inserted to a PCB from top to bottom through the drilled holes, followed by soldering.
Depending on the design, the plated through hole pad size may be connected to a ground plane or it's larger than usual. These require more heat. You may notice that the solder is kind of "sticking" but really, it's just blobbing up. You may need: larger soldering iron tip adjust th...
Before diving into the pad stack, it may be valuable for the reader to understand the general process of creating a PTH. The design of PTHs includes the dimensioning of the hole and the capture pad, which encircles the drilled hole and extends radially an additional distance away from the h...
The device utilizes one -way admission valve to produce a large amount of air currents, utilizes toper blowing nozzle increase blowout airflow simultaneously to high -efficient, the safe soldering tin with on the PCB through -hole pad is detached. In addition, the device is energy -concerving...
a. Suitable THT size should be picked up. When it comes to PCB design with multiple layers and ordinary density, THT should be picked up with through hole parameters being 0.25mm, 0.51mm and 0.91mm respectively for vias, pad and isolation area. High-density PCBs can also select through ho...
