Practice makes perfect and soldering needs a lot of it...This 100x100mm board contains all the features you will need in order to practice your soldering, improve your skills and boost your confidence. Depending on your soldering experience, it comes in handy both as an exercise tool and as a quick way to warm-up before a soldering session.Watch my video for all the necessary details: https://www.youtube.com/watch?v=czXJevPWIsA Main features of this soldering practice board:- Castellated holes (plated half-holes) in four (4) different sizes, along all the edges of the board. - Six (6) types of pads in a total of eleven (11) rows, with different heat dissipation characteristics.- Large pads with very high heat dissipation, from 2.5x2.5mm up to 7.0x7.0mm sizes.- Tiny pads in four (4) large groups, for precision soldering and pad bridging practice.- Cold section with four (4) different types of pads, interconnected with traces for varying heat dissipation.- Rails in various widths, for long, uniform and continuous soldering using different tip sizes.- Battery connector section with mounting holes for XT60, XT30, PH2.0 and BT2.0 connectors.- SMD section for surface mounted components, with different spacing.- Board mounting pads for a RX5808 module - the pad spacing should fit other surface-mounted boards too.- Antenna connector pads for SMA, MMCX, IPEX and uFL connectors.The spacing of the pads and the castellated holes becomes smaller as you reach the end of each row, for more challenging soldering conditions. You can add wires between the pads to increase heat dissipation even more.The XT60 holes can be used for holding the board with the alligator clips of helping hands. There are also mounting holes on the board for your own custom stands/holders. Check the info sheet for more details on my Ultimate Soldering Practice Board: http://www.mutefpv.com/uspbinfo Ordering details:- Join PCBWay here: http://www.mutefpv.com/pcbway or Sign-in and add my design to your cart.- Make sure the "castellated holes" option is checked / enabled (on checkout).- Choose your desired surface finish: HASL will be like having pre-tinned pads. OSP adds an organic coating on the copper pads that goes away as you apply heat with your soldering iron. If you want something more premium, go for the ENIG (immersion gold) option.- Insert the quantity you want.- Select the "solder mask" color you want (this is the color of the PCB board).- Select the "silkscreen" color you want (this is the color of the text, logo and borders on the board).
