What is the Arlon 45N PCB Material?

The Arlon 45N PCB Material is known to be tough, and has a high temperature of glass transition with a value of 175 degrees Celsius by DSC. It is a prepreg system and multifunctional epoxy laminate, which is useful in different higher layer count multilayer boards. Making use of the conventional conditions for FR-4, you can process them.

They are relevant in applications such as mother boards and black planes, BGA packaging, multilayer boards of high layer count, and automotive applications. Let’s go into details of the features of this multifunctional material.

What are the Features of the Arlon 45N PCB Material?

The features of the Arlon 45N PCB Material is as follows

Great for a large number of lead-free applications. This PCB material serves different lead-free applications. This means that these applications don’t use lead because of their harmful nature.

Its flammability rating is UL-94 V0. This is the standard the UL has set to help in testing a material’s flammability which means that on any vertical specimen, burning stops in ten seconds.

Resistant to solder and Measling shock defects

It has a high glass transition temperature at 175 degrees Celsius. This means that this pcb material has a strong ability to develop glassy-state properties like rigidity, stiffness, and brittleness upon cooling.

Meets the IPC4101/26 specification and description

Also, it is RoHS/WEEE compliant. This means that it has been regulated for any hazardous substance utilized in manufacturing electronic and electrical equipment. This means that this pcb material has passed the RoHS/WEEE compliance.

Recommended Process Conditions of the Arlon 45N PCB Material

The recommended process conditions of the Arlon 45N PCB material is as follows.

For the Arlon 45N, process the inner layer through strip, etch, and develop making use of the standard practices of the industry.

Furthermore, on the inner layers, make use of brown oxide. Also, adjust the dwell time present in the oxide bath. This makes sure that there is uniform coating.

In addition, bake the inner layers in the rack for an hour at a temperature between 225 degrees Fahrenheit and 250 degrees Fahrenheit. This should be done before lay-up. Also, the prepreg should be vacuum desiccated for about 8 to 12 hours before you laminate.

For the lamination cycle, pre-vacuum it. This should be done for thirty minutes. Also, control the rise in heat to 8 – 12 degrees Fahrenheit every minute between 210 to 300 degrees Fahrenheit.

In addition, the product temperature during the start of cure should be 360 degrees Fahrenheit. Also, the cure time should be 90 minutes. Lastly, cooling down should be done under a maximum pressure of 12 degrees Fahrenheit.
