foreign body under the feeding device, and the spring is aging, or poor electrical), resulting in insufficient or poor retrieval of materials and throwing materials, there is damage to the feeding device. Countermeasure: Adjust the feeding device, clean the feeding platform, and replace the bad parts or feeding device. When there is a throwing phenomenon, you can first ask the on-site personnel to describe it, then, we can find out the problem based on the observation and analysis, so that we c

PCB Optimization Design (reprint)

PCB Optimization Design (i.)2011-04-25 11:55:36| Category: PCB design SMT technology is now very mature and widely used in electronic products, therefore, electronic product designers need to understand the SMT technology common Sense and manufacturability design (DFM) requirements. SMT process products, at the beginning of the design should be integrated into consideration of the production process, raw material selection, equipment requirements, device layout, test conditions and other element

Split welding of BGA IC

planting.The use of small tin planting board is to fix the IC under the tin planting board, scrape the tin paste and then blow the board together, compress the ball and then remove the IC. It has the advantage of tin planting Board during hot air blowingBasically no deformation, if there is a lack of feet or the tin ball is too small after a tin planting phenomenon can be secondary treatment, especially suitable for new users. I usually use this tin board. The method we will introduce below is

PCB Virtual Welding Analysis

Wave automatic soldering technology has been used in the electronics industry for many years, but the late failure of solder joints is still a headache, which greatly affects the quality and reputation of electronic products.This paper intends to make a preliminary study and discussion on the basis of practical experience.The so-called "late failure of solder joints", refers to the surface appears to be the quality of the solder, there is no "lap weld

How can I pad the IC on the chip adapter? .doc ZZ

3004202330-1-Wang Huiquan-1. How to weld the smd ic on the chip adapter board? Prepare tools for welding the integrated circuit of the table, such as a good soldering iron (the finer the head, the better) and solder paste. For fine pin spacing, first apply a layer of solder paste on the clean pad, and then use a clean constant temperature soldering iron to thin a layer of Solder Pad (according to observatio

repair process is still quite complicated. Below, the author describes the repair steps in detail. 1. Peel off twisted-pair wires Like the "Earth-type" twisted-pair repair method, to repair twisted pair, the first thing to do is to peel off the twisted pair. In the stripping of twisted pair, must pay attention to, do not peel too long, because this kind of repair method, is directly with soldering iron. The length of the Twisted strand is 5cm. Twi
