1.1 Common problems
A.Orifice bubble
B.The plug hole is not full
C.Resin and copper layering
1.2 Consequences
A. There is no way to make a pad on the hole; the hole is hidden, the chip is mounted and blown, also called out-gassing
Nowadays, the resin plugging technology is mainly used in the following products:
1. POFV technology resin plugging;
2. Inner layer HDI resin plug hole;
3. Through hole resin plugging.
The process of resin plugging has been widely used in the PCB industry in recent years, especially in some products with high layer and large plate thickness. It is desirable to use resin plugging to solve a series of problems that cannot be solved by us
When the capacitor is connected to the DC power supply, it accumulates power and continues to supply power for a while after the power is turned off. In other words, the capacitor acts like a rechargeable battery that can store or release electrical energ
The complete name of the relay is an electromagnetic armature relay, which is separated from the solid-state relay. The full name is not commonly used, and is usually referred to as an abbreviation. Some people refer to relays as motor relays, but when it
The AC-DC power supply can convert alternating current (AC) into direct current (DC) for general electrical appliances, and the voltage available after conversion is usually low. Therefore, although the name is the “power supply”, in fact, the device itse
Transformers vary in size from small acoustic impedance matching parts in audio equipment such as microphones to state-of-the-art power companies that weigh several tons of super monsters. Basically, as long as the required voltage is different from the v
The main usage of SMT reflow oven plus nitrogen (N2) in the PCBA processing is that to reduce the oxidation of the soldering surface and improve the wettability of the solder. As nitrogen is a kind of inert gas, it is not easy to produce compounds with me
PTF (polymer thick film) should also be considered as a kind of flexible circuit board (Flex Cable), which uses a screen printing technique to print a conductive layer on PET. The circuit is formed on the substrate, and some more elaborately, a layer of i
