Part 1: THT Assembly PCB assembly for through-hole technology is different than the Surface mount technology as THD Can not be mounted on top of the PCB so there are two procedures to follow for THT assembly. One of them is the traditional Manual method and second one is automatic method. Some steps are discussed here in detail. Step1: Component’s placement Themanual methodof components placement ...

If you have the opportunity to pick up a printed circuit board and observe it alittle, you willfind that there are many large and small holes on the circuit board. Take it up and look at the lamp on the ceiling, and you will find many densely packed small holes. The holes are not placed in a good place, each hole is designed with a purpose. Commonly drilled holes in our printed circuit board(PCB) ...

As the current design of portable products is developing toward miniaturization and high density,the difficulty of PCB design is also increasing, which puts forward higher requirements for PcB processing technology. Most of the current portable products use the BGA package with a pitch of less than 0.65mm, and the design process of blind and buried holes is used. So what is a blind and buried hole...

What is a Half Hole PCB? Half-hole PCB means that one drill hole (drill, gong groove) is drilled, and then the second drill, shape process, and finally half of the metallized hole (groove) is reserved. Module PCBs are basically designed with half holes, mainly for the convenience of welding, small module area, and many functional requirements. The usual half hole is to design a hole on the edge of...

Aluminum PCB has the ability to dissipate heat from electronics, it has a standard FR4 laminate and an aluminum core. The circuit board effectively helps dissipate heat with its unique thermal insulation layer. These printed circuit boards are most widely used in applications involving tight tole rances and high power. Choosing the type of aluminum circuit board depends largely on its use. A lumin...

1. Mechanically controlled depth drilling In the traditional manufacturing process of smt patch multilayer boards, a drilling machine is used to set the Z-axis depth of drilling, but there are some problems: a. Only one can be drilled at a time, and the yield is very low. b. The table of the drilling machine must be level, and the drilling depth of each spindle must be the same. Otherwise, it is d...

Copper is a common material used in circuit boards, especially for the conductive traces that connect various components and elements of the circuit. However, it is possible that the term "copper in the circuit board hole" may refer to different things, and I'll cover a few possibilities: Plated Through-Holes (PTH): In traditional circuit boards, plated through-holes are holes drilled through the ...

A Thick Copper PCB, also known as a Heavy Copper PCB, is a type of printed circuit board that features copper traces and planes with significantly higher copper thickness compared to standard PCBs. While standard PCBs typically have copper thickness measured in ounces (e.g., 1 oz, 2 oz), Thick Copper PCBs can have copper thicknesses ranging from 3 oz to as high as 20 oz or more. The increased copp...
