BS EN 61249-4-18:2013

What is BS EN 61249-4-18 - Prepreg materials used in printed boards about?  

BS EN 61249-4-18 is the fourth part of an international standard used for printed boards and other interconnecting structures. By using BS EN 61249-4-18 you can manufacture better quality prepreg materials used in printed boards.  

BS EN 61249-4-18 specifies the requirements for properties of prepreg that is mainly intended to be used as bonding sheets in connection with laminates according to IEC 61249-2-39 when manufacturing multilayer boards according to IEC 62326-4. Multilayer boards comprised of these materials are suitable for lead-free assembly processes. This material may be also used to bond other types of laminates. 

Prepreg according to this standard is of defined flammability (vertical burning test). The flammability rating on fully cured prepreg is achieved through the use of brominated fire retardants contained as an integral part of the polymeric structure. After curing of the prepreg according to the supplier’s instructions, the glass transition temperature is defined to be 170 °C minimum. 

Who is BS EN 61249-4-18 - Prepreg materials used in printed boards for? 

BS EN 61249-4-18 on Materials for printed boards and other interconnecting structures is useful for: 

• Aerospace  
• Manufacturer of aircrafts 
• Manufacturer of electronic components 
• Manufacturer of automotive parts  
• Electronic engineer 
• Aeronautical engineer 

Why should you use BS EN 61249-4-18 - Prepreg materials used in printed boards?  

Printed circuit boards (PCBs) are used to mechanically support and electrically connect electronic components. These components are connected by using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate.  

BS EN 61249-4-18 specifies the materials that are used in manufacturing the printed boards according to their operational requirements. With the help of BS EN 61249-4-18, you can identify the properties that are useful in avoiding the defects which may impact the materials. This helps in determining the characteristics of B-stage prepreg. These characteristics are used according to their qualification and quality conformance testing of prepreg materials.  

By applying BS EN 61249-4-18 you can deliver this Prepreg in accurate size and prescribed mode specified by your client. This helps in manufacturing good quality prepreg materials used in printed boards and other interconnecting structures.
