Innovative Materials For Harsh Environments

High Temperature Durable Label

Polyonics thermal transfer printable polyimide label

materials include durable next generation top coats

formulated to resist abrasion, not soften or yellow at high

temperatures and withstand the harsh highly active fluxes. The

materials include thermally stable polyimide and aggressive

pressure sensitive adhesives (PSA) that are designed to

remain affixed to PCBs through wave solder, reflow and

high pressure washes. They have also been rigorously tested

and approved by flux makers Alpha Metals and Kester and

cleaning solutions makers Kyzen and Zestron.

Durable PCB Labels for Harsh Flux and Abrasion Resistance

An Evolving PCB Industry

PCB manufacturers are

constantly evolving their

soldering and wash

processes to increase the quality

and reliability of their products

while reducing cycle times and

costs. Highly active ORH1, water

based and no clean fluxes along with higher soldering

temperatures are all popular along with high pressure

washes. The miniaturization of electronics also requires

fixturing that can cause abrasion to labels.

Next Generation Label Materials

Polyonics has developed

a growing family of label

materials specifically

designed to withstand the

types of highly active fuxes

used in today’s harsh PCB

manufacturing processes. The

materials include durable next generation thermal

transfer printable topcoat chemistries that are abrasion

and chemical resistant, maintain a high level of contrast

and remain readable throughout even the harshest

process. In addition, several ESD-Safe™ options are

available that help protect ESD sensitive devices.

Improved ORH1 and Abrasion Resistance

A second benefit of the durable top coat chemistry

is its increased abrasion resistance when directly

contacted at elevated temperatures during

manufacturing. Some PCB processes require labels to be

in contact with material handling devices, conveyors,

robots, etc., or with fixtures used to hold circuit boards,

components, etc. during soldering and/or cleaning. In

these applications, standard labels may soften, become

easily scratched and unreadable.

The image below compares the dramatic effects

exposure to ORH1 and abrasion has on standard barcode

labels (bottom) and the Polyonics XF-731 barcode label at

the top. The XF-731 maintains virtually the same contrast

and readability before and after processing while the

standard label is unreadable.
