Must PCB be Baked and Then Mounted?
PCB is a kind of electronic parts, is also the carrier of the whole PCBA, other electronic parts are mounted on the PCB pad, play their respective electronic communication function. Patch must be used PCB. PCB in the production out of the general are vacuum packaging, in the pick and place machin...Read more -
Reverse Current Blocking Circuit Design
Reverse current is when the voltage at the output of a system is higher than the voltage at the input, causing current to flow through the system in the reverse direction. Sources: 1. the body diode becomes forward biased when the MOSFET is used for load switching applications. 2. a sudden drop i...Read more -
Do you know EMC Filtering?
I. Overview The three elements of electromagnetic interference are the source of the interference, the interference transmission path, the interference receiver, EMC around these issues for research. The most basic interference suppression techniques are shielding, filtering, grounding. They are ...Read more -
What are the defective products of processing solder joints?
After SMT reflow soldering we will encounter some defective phenomena, these SMT processing soldering defects will directly or indirectly affect the quality of the product. These defective phenomena are clear SMT operators on the patch processing defects judgement, so as to provide the industry b...Read more -
Solder Joint Quality and Appearance Inspection
With the progress of science and technology, mobile phones, tablet computers and other electronic products are light, small, portable for the development trend, in the SMT processing of electronic components are also becoming smaller, the former 0402 capacitive parts are also a large number of 02...Read more -
The significance of spi straight through rate control
SMD processing first need to scrape a layer of solder paste on top of the pcb pad, solder paste printing needs to be done after the quality of the test, test the name of the machine is called spi (solder paste testing machine), the main test of the solder paste printing whether there is offset, p...Read more -
Design Considerations for Multistage Amplifiers
There are several important considerations to keep in mind when designing a multistage amplifier. Here are some of the key factors to consider: Request a Quote Now for PCB Manufacturing and Assembly Gain and Bandwidth Requirements The first step in designing a multistage amplifier is to determine...Read more -
PCBA Short Circuit Troubleshooting Solution
Once the PCB design is completed, we need to check it for all the project features. Just like when we finish the test paper by ourselves, we should do a simple analysis and check all its problems again, so as to ensure that we won’t make a big mistake due to negligence. The following neoden...Read more -
What are the hidden risks of aging ceramic capacitors?
Q: Ceramic capacitors are affected by aging phenomena Ceramic capacitors are affected by aging phenomena associated with changes in the dielectric crystal structure, which manifests itself as changes in capacitance and dissipation factor after initial firing of the dielectric material. Consistent...Read more -
