ESD effect when Clone PWB Board
Clone PWB Board need to prevent the negative effect of ESD on them, in order to minimize the negative effect and have a better PWB Board clone outcome, below measures must be made to ensure the goal being achieved:
1. cabinet grounding track on the top and bottom shouldn’t print mask resist then it can be the discharge electrode for pwb board clone if the board is put outside of metal cabinet or shielding box;
2. Design a round grounding on the circuit when clone pwb board:
1> Loop circuit being placed when clone pwb board except the rim connector and cabinet grounding;
2> ensure all the annular ring width greater than 2.5mm when clone pwb board;
3> connect the annular ring by through vias each 13mm when clone pwb board;
4> connect the common grounding of multilayer circuit with annular ring grounding;
5> as for the double side pwb board installed outside metal cabinet or shielding, should put the annular ring grounding with common circuit;
3. clone pwb board a grounding track aside each one of signal track in where the ESD can be penetrated directly;
4. I/O circuit should be cloneed to close the corresponding connector;
5. for those circuits which are more susceptible to ESD, should be clone in the centre area of pwb board, because other circuits can provide the protection for them;
6. clone series resistor and magnetic bead on the receiving terminal, as for those cable driver which is more liable to get shock by ESD, can also consider clone pwb board with resistor and magnetic bead at the receiving terminal;
7. instant protector normally should be placed on the receiving terminal of pwb board. Use the short and thick wire connect the cabinet grounding.
the supreme court has already proclaimed the business secret or intellectual property obtained from self-research or through clone PwB don’t belong to the unfair competition action. Circuit Engineering Co.,Ltd has commited to pwb board clone technology research and service for over two decades. and have ever reverse engineering then clone or copy the electronic printed circuit board from different industries, as well as the pcb board manufacture and prototype building. and we have great advantage over the printed circuit board clone cycle control, research and development as well as the cost analysis.
Nowadays, electronic products are being updated in fast speed; and PWB board CLONE from our company in the base of completely master the traditional PWB board structure or its basic circuit, furthermore, is base upon the self research and development, include the software upgrade and product second phase development; and we will dedicate to clone PCB with 100% exact the same functions as original sample given by customers.at the same time, we also decrease the PWB BOARD clone cycle refers to the pcb board with blind or buried vias, effectively save customer time and energy, low down its cost. and which is also one of the reasons for us to be favor by most of our clients.
