Before PCB soldering,check the PCB to be soldered to ensure that it is clean.The oily fingerprints and oxides on the surface should be removed so as not to affect the tin.When soldering the PCB by hand, if conditions permit,you can use a soldering station or the like to fix it to f...
In electronics PCB Manufacturing, Assembly and Rework, the metals to be joined are the leads of the electronic components (thru-hole or SMD) with the copper tracks on the PCB. The alloy used to join these two metals is solder which is basically tin-lead (Sn-Pb) or tin-silver-copper (S...
After the solder bead has cooled down, you should check to make sure that the SMD is securely attached to the PCB pad. Let the pad and SMD cool for a few minutes after applying the bead of solder. Then, make a close visual inspection, using a magnifying glass, if necessary. You shoul...
Request PCB Manufacturing & Assembly Quote Now What is Desoldering? There is a very important think to know concerning the use of solder. The fact is, you can remove it using a technique called desoldering. This is important in cases where you need to take out a component or make correction...
How to Get BGA Perfectly Soldered on PCB in SMT Assembly Process SMT assembly mainly consists of the following steps: • Solder Paste Printing; • SPI (Solder Paste Inspection) (Optional); • Chip Mounting; • Reflow Soldering; • AOI (Automated Optical Inspection); • AX...
Before learning how to solder, it's always wise to learn a little bit about solder, its history, and the terminology that will be used while discussing it. Solder, as a word, can be used in two different ways. Solder, the noun, refers to the alloy (a substance composed of two or ...
Surprisingly, although soldering is the core process of electronics PCB assembly, few people know how to solder reliably. They often become proficient at hiding defects, but that’s a completely different and unacceptable ability. Visually acceptable connections are not necessarily reliable connections. ...
Elimination of solder joints:Boards with embedded components do not require solder joints, reducing the risks of mechanical failure. Improved durability: Your PCB designs will be more resistant to shock, vibration, and temperature fluctuations, ensuring they perform well even in harsh environments. ...
Advanced technologies can never be fully flourished until they are applied on up-to-date equipment. In terms of PCB fabrication and assembly, leading equipment and their required specifications include: • Solder paste printing accuracy. Whether it is capable of printing tiny components such as 010...
Solder mask, also called solder stop mask, is a PCB process used to protect metal elements on a circuit board from oxidation, and to keep conductive bridges from forming between solder pads. It's a critical step inPCB manufacturing, especially if reflow or solder bath is used. These techniqu...
