Electric/electronic parts They come in a variety of sizes and mounting techniques. The classic is through-hole technology (THT) and the modern counterpart is surface-mount technology (SMT). Unfortunately, these two technologies are built into nearly all electronic devices, but require different soldering methods. dilemma? yes and no.
The use of two techniques affects the soldering process. For the EMS provider, this means each board has to go through her two soldering processes. One for surface mount components (reflow method) and one for components for through-hole assembly (wave soldering). Not to mention the two soldering steps significantly increasing the cost and production time. Additionally, two soldering systems must be available. But there are other drawbacks as well. High temperatures shorten the life of electronic components. Manually placing the parts in his second soldering cycle on the wave bath greatly increases the risk of incorrect placement.
With this in mind, consider circuit protection for fully automatically assembled PCBs. Mounting the fuse holder on the SMT board is very advantageous and can also be soldered in a reflow process. Her OGN from SCHURTER is a prime example. Open fuse holders are designed for his 5×20 fuses of various current ratings and tripping characteristics. If desired, it can also be easily converted into a closed fuse holder with a cover.
