PCBA Thermal Pads Design Requirements
1. What is thermal pad The so-called thermal pads, refers to the bottom of the components with the metal side of the heat dissipation solder pads, usually relatively small power, mainly through the heat dissipation pads on the heat dissipation holes to the ground layer. In order to better heat di...Read more -
How to Improve The Production Efficiency of SMT Machine?
In the production line of SMT, the most important concern is often how to control production costs and improve production efficiency. This involves the problem of the SMT machine throwing rate. The high rate of SMD machine throwing material seriously affects the SMT production efficiency. If it i...Read more -
The 6 Steps of The Basic Process of Multilayer Circuit Board
The production method of multilayer boards is generally done by the inner layer graphics first, then by printing and etching method to make a single-sided or double-sided substrate, and into the designated layer between, and then by heating, pressing and bonding, as for the subsequent drilling is...Read more -
Reflow Oven Maintenance Methods and Precautions
Reflow Oven Maintenance Methods Before inspection, stop the reflow oven and lower the temperature to room temperature (20~30℃). 1.

What are the daily checks required for wave soldering machine?
What are the daily checks required for wave soldering machine? Check the flux filter and remove any excess flux residue. The flux filter is cleaned with water once a week, the inside of the extraction hood is cleaned weekly and the spray system is checked for uniformity of spray. The nozzle shoul...Read more -
Analysis of The Causes of Continuous Soldering with Wave Soldering
1. inappropriate preheating temperature. Too low a temperature will cause poor activation of flux or PCB board and insufficient temperature, resulting in insufficient tin temperature, so that the liquid solder wetting force and fluidity becomes poor, adjacent lines between the solder joint bridge...Read more -

SMT No-clean Rework Process
Preface. The rework process is consistently overlooked by many factories, yet the actual unavoidable shortcomings make rework essential in the assembly process. Therefore, the no-clean rework process is an important part of the actual no-clean assembly process. This article describes the selectio...Read more -
Why Do I Need A “0 Ohm Resistor”?
The 0 Ohm resistor is a special resistor that has to be used for a number of applications. So, we are actually in the process of circuit design or often used to a special resistor. 0 ohm resistors are also known as jumper resistors, is a special purpose resistors, 0 ohm resistors resistance value...Read more
