Factors that Affect Conformal Coating
With so many types of conformal coating and various methods of application, it is important to consider the primary factors of conformal coating, in order to achieve defect-free coating and highest reliability of the final device. Primary Factors Choice of conformal coatingSelecting the right conformal coating is necessary to achieve better protection ViscosityThe viscosity of the conformal coating used affects the method of application, cure time, thickness and coverage Equipment parametersFor example, the speed and height of application Masking keep-out areasAre there any areas that should not be covered by...

Different Types of Flux
There are different types of soldering flux, like liquid flux, tacky flux, flux core, and flux in solder paste. Each type has its own benefits and works well for specific soldering jobs. The one you choose depends on things like the kind of soldering you're doing, how easy it is to reach the joint, the way you want to apply the flux, and the needs of your soldering project.  There are 4 different kinds of flux, each of which has its own characteristics and serves different purposes: Liquid Flux  Liquid consistency...

Why Clean "No-Clean" Fluxes?
No-Clean flux increased in popularity as it leaves behind little to no residue during the soldering process, compared to rosin or water soluble flux. This reduced the need for extensive cleaning of circuit boards after soldering, saving companies much time and cost, making it an ideal choice for many production line.  The residue left behind from no-clean flux or paste is considered to be so little that it does not require cleaning in most cases, and the resulting electronic device or machine can still function with no disruptions. While the general consensus... Read more...
5 important tips for cleaning electrical contacts
Why do you need to clean electrical contacts?  Maintaining clean electrical contacts is essential for the optimal performance of electronic devices, appliances, and machinery. The presence of dirt and debris can lead to compromised connectivity, intermittent functionality, and, in severe cases, total electronic failure. A contact cleaner comes in handy in such a situation. It is a solvent cleaner designed to remove contamination from electronic contacts or other electronic components. Here are five tips to ensure a smooth cleaning process for your electronics:    Disconnect the Power Source  Turning off the... Read more...

How do dendrites grow on electronic assemblies?
  Electrochemical Migration occurs when dense current leakages cause conductive metal filaments across a printed circuit board (PCB), resulting in dendrites and surface contamination. These dendrites can cause field failures and can be intermediate or permanent. PCBA reliability is influenced by soldering materials' chemistry, residues' activity, and other factors like PCB material composition, uncleaned flux residue, active chemistry concentration, board surface roughness, and environmental conditions like humidity and temperature. Metal Dissolution  A strong alkaline condition, typically caused by environmental pollutants or flux residue, attacks the anode and power-leading contacts, forming... Read more...
