█ Electronics Manufacturing Technical Articles

Cleaning PCBs before conformal coating removes potentially harmful and unknown contaminants from the board's surface resulting in better adhesion of the conformal coating and thereby preventing delamination. Cleaning PCBs can ultimately prevent issues like leakage current, electrochemical migration and coating failures. From a production standpoint, it can help ...

Cleaning No-Clean Fluxes Prior to Conformal Coating

A customer called the Helpline seeking advice for cleaning no-clean fluxes prior to applying a conformal coating. The customer's assemblies were manufactured with a no-clean rosin based solder paste (ROL0) and were cleaned with an isopropyl alcohol (IPA) wash. After cleaning, a white residue was sometimes found in areas with high paste ...

Setting Up a Conformal Coating Facility

The set up of a turnkey conformal coating production line or facility, whether it is a batch or inline process, has many similar characteristics. Whether the coating application is based around a high volume selective coating robot, a batch dip coating system or a spray booth, the process requirements tend to be the same. This bulletin reviews ...

The Effects of Plasma Treatment Prior to Conformal Coating

The corrosion of Nickel-Palladium-Gold (Ni-Pd-Au) finish terminals in humid environments is known to be reduced with the application of a conformal coating such as acrylic. Corrosion has a higher rate of occurrence around the terminal 'knee' of a surface mount component, which may be reduced with the application of conformal coatings. Although radio frequency (RF) plasma processing is generally known to enhance conformity of conformal coating to surfaces through ionic bombardment, the effect on the functionality of assembled printed circuit boards (PCB) is not as well known. The purpose of this study is to assess whether RF plasma processing can enhance the adhesive and coverage qualities of an acrylic conformal coating on PCBs

Conformal Coating Defects

Conformal Coatings are polymeric materials used to protect circuitry, parts, and related components. They are most commonly used to protect printed circuit boards (PCBs) and electronic devices. However, conformal coatings can be applied to a wide variety of materials, including metal, plastic, silicone, ceramics, glass, and even paper. We use the term "substrate" to refer to an object or material that's been coated with a conformal coating.

█ Printed Circuit Board Assembly & PCB Design Forum

How to adjust stencil frame size for MPM speedline accela? -- How can I adjust the stencil frame size on my MPM speedline accela? is there an automatic option or I need to do it manually?

Bridge Defects -- Is a bridge considered a defect, if adjacent pads/component leads are electrically connected (common) via a trace but said trace is covered in solder mask ? Essentially, of course bridges are never a target but is rework required/de-bridging required if the two leads OR components are connected on the same track? Even though solder mask is to prevent flow of solder, since these are indeed connected on the board level, a bridge in that case would become a process indicator correct? TLDR: if two components lead/pads are connected via trace, this is considered common conductors therefore acceptable as a bridge rather than defect?
