Modeling provides the powerful functionality required by each circuit board designer. Complete Glossary of Professional Terminology for printed circuit board assembly. In certain design types, they also provide the high-speed IP that customers need.
Its professional type of circuit board products can be selected based on IPC6012, a virtual reality production team.
The design of high-precision manufacturing systems for the dynamic, mechanical, electronic, information, mechanical, and other professional manufacturing industries.
The development of high-resolution printing technology and new high-precision printed circuit board technology has achieved data compression, and has the requirements of high production efficiency, low production cost, easy maintenance, high automation, and suitability for mass production.
All electronic devices must use materials that prevent damage, and all circuit boards must also have a guaranteed lifespan, which is a very important aspect of high temperature.
Nothing will come in. The black and black on the printed circuit board, where there are burrs, will all be used, and you need to point out the correct areas.
All electronic components in the factory should be carefully inspected and no imitation water should appear. Use a tool to wipe the entire foot of the component. If it cannot be set, it can be set. Long ago, when encountering employees who have just completed the PCBA project and did not have clear regulations on the bottom, confirm the condition of the circuit board according to the above standards.
If the copper foil left by a technician's finger pad when repairing a circuit board is cut while removing red, green, and blue tin, then remove the circuit board.
Do not place all components in front of the circuit board, as it may cause unnecessary downtime when the circuit board is processed and put down.
When using a high-temperature furnace, attention should be paid to the heating part not involving the required welding points, otherwise it may cause the welding pad to fall off and affect welding.
Do not press the relevant wires behind connectors such as resistors, capacitors, switches, etc., and do not require the overall structure of the PCB to be "suspended" or "one touch".
If you want to replace SMD ceramic capacitors with SMD ceramic capacitors, the dielectric of SMD ceramic capacitors is generally ceramic or aluminum, and there are two layers of thin film dielectric. Therefore, when you replace SMD ceramic capacitors with plug-in SMD capacitors, it is easy to generate leakage phenomenon; In addition, the dielectric thickness of SMT ceramic capacitors is generally 01 μ m~02 μ m. If using 02 μ M or 08 μ M's ceramic products replace SMD ceramic capacitors. Generally, the thicker the thin film, the better the quality of leakage, and vice versa. High frequency ceramic capacitors generally have several allowable error ranges. If the frequency is greater than 1 GHz, they cannot be used in parallel because the resonant characteristics of the capacitors change with the continuous change of frequency.
