· Flexible PCBFlexible Printed Circuit referred to as FPC. It is made into conductor circuit patterns using light pattern expose transfer and etching processes on the surface of a flexible substrate. The surface and inner layers of double-sided and multi-layer circuit boards are electrically connected through metalized holes.
The AOI equipment finds these issues by capturing images of the inner PCB surfaces looking for any possible issues in terms of displacement polarity etc. AQL Short for acceptance quality limit AQL refers to the acceptable number of defective boards produced within a production run. These are identified counted and removed during inspection.

· It is suitable for all kinds of electronic waste and PCB such as mobile boards TV panels computer boards washing machines old fridge panels FPC flexible circuit boards etc. It is mainly used in PCB Recycling Plant. Working principle Using the nature gas as the heat the tin will be loose when temperature is up to 0 C. When the roller works electronic components will be separated because of the scraping function between PCB. So we can dismantle electronic components from PCB
Manual soldering with wire will not have this consistency. Without investing in a selective solder machine you may want to look at flux-coated solder washer prefroms. The outer inner diameters and thickness of the washer preform can be designed to achieve complete barrel fill. The washer is hand-placed and melted with a hot-air gun.

· Ceramic PCB is a thermal conductive organic ceramic circuit board with thermal conductivity of 9-20W/m.k prepared at a temperature below 250°C using thermally conductive ceramic powder and organic adhesive ceramic PCB types by material including alumina pcb Aluminum nitride ceramic PCB Copper clad ceramic PCB Zirconia ceramic base PCB.
1. Calculation in PCB Trace Resistance . Calculating the PCB trace resistance is as simple as using the ohms law with the known parameters. Most design suits and development environments have integrated PCBs trace resistance calculator which can estimate the resistance of the final copper trace on the board by providing the required and manufacturing profiles.
The final product results in a plastic sheet with a photo negative of the PCB in black ink. For the inner layers of PCB black ink represents the conductive copper parts of the PCB. The remaining clear portion of the image denotes the areas of non-conductive material. The outer layers follow the opposite pattern clear for copper but black refers to the area that ll be etched away.
