Today, let’s continue to learn about the difference between aluminum base boards and FR-4 in manufacturing difficulty, application range, and coefficient of thermal expansion.

Today let’s continue to talk about the difference between aluminum base boards and FR-4 in thermal conductivity and mechanical strength.

As we all know that, FR-4 and aluminium-base material are common raw materials in PCB manufacture. Do you know what’s the difference between them? Today let’s learn about that. Let’s start from their definition

Now, let’s continue to learn another 4 precautions in this article. 1. Film Thickness Control 2. Coating Environment Requirements 3. Selective Spraying 4. Whole Board Automatic Spraying

Here is our new product with red solder mask, and the copper foil thickness of outer layer is 4OZ, and the surface treatment is as same as the last Rogers products--lead-free hot air solder level.

This time we will talk about the other precautions of covering conformal coating on PCB. These precautions are mainly formulated the workers to take care of the covering conformal process, to making better PCB products with covering conformal. 1. Personal Protection 2. Post-Spray Cleaning 3. Coating Thickness 4. No Coating Areas

Today let’s learn about several common methods for removing conformal coating from a PCB, each with its specific application scenarios and advantages. 1. Using chemical solvents 2. Micro-abrasion 3. Mechanical method 4. Desoldering through the protective coating

Today we will continue to learn about the precautions of conformal coating process.

It have been a long time since we send out our new products, here it is! The new PCB is made by Rogers material, and using lead-free hot air solder level technique.

So let’s continue to talk about which parts and components that can’t be covered by conformal coating. 1.Heat dissipation related components 2.Specific resistance components 3.Electrical connection and adjustment components 4.Sound and display components 5.Power and protection components 6.Interface and connection components 7.Light-emitting diodes (LED) 8.Grounding components

Let's continue to learn about the common quality requirements of conformal coating. 1.No runs and drips 2.Coating uniformity 3.Coating and component surface quality 4.Local isolation areas

Let's continue to learn about the specific operational requirements. 1.Work environment 2.Personal protection 3.Tool and container handling 4.Circuit board handling
