Printable thermal interface gels solve automotive reliability challenge

Cus­tomers look­ing for high-reli­a­bil­i­ty one- and two-com­po­nent ther­mal inter­face gels that can be print­ed final­ly have a solu­tion they can count on.

Cus­tomers are often faced with the chal­lenge of using either a ther­mal inter­face mate­r­i­al that can be print­ed, or one that can endure auto­mo­tive reli­a­bil­i­ty which includes rig­or­ous vibra­tion tests.

Hon­ey­well recent­ly launched two, new hybrid ther­mal hybrid prod­ucts that meet the chal­lenge of being both print­able and high reli­a­bil­i­ty. The first is a two-com­po­nent ther­mal hybrid gel HLT3000, the oth­er is one-com­po­nent pre-cured HT4500 ther­mal hybrid gel.

Both of these prod­ucts have low­er vis­cos­i­ty and enable thin­ner bond­lines com­pared with their reg­u­lar hybrid ther­mal gels coun­ter­parts. This means that these hybrid gels can be used for print­ing process as well as only being able to be dispensed. 

This advan­tage is par­tic­u­lar­ly impor­tant for users that find them­selves in one of the fol­low­ing two scenarios:

1. The user is using a ther­mal grease but finds that he can­not meet the auto­mo­tive reli­a­bil­i­ty because they expe­ri­ence pump-out or dry­ing issues.
2. The user likes the reli­a­bil­i­ty of hybrid ther­mal gels, but don’t want to invest (or do not have access to) dis­pens­ing equip­ment. They would pre­fer a print­ing process.

These two prod­ucts were orig­i­nal­ly designed based on spe­cif­ic cus­tomer feed­back. The HLT3000 was devel­oped after the cus­tomer real­ized that he need­ed a two-com­po­nent gel to replace grease with high reli­a­bil­i­ty. Due to their ini­tial low­er-vol­ume planned pro­duc­tion, they did­n’t want to invest in a dis­pens­ing machine. How­ev­er, the final appli­ca­tion was an auto­mo­tive appli­ca­tion for an elec­tri­cal con­trol product.

The sec­ond prod­uct, the ther­mal hybrid gel HT4500 was also orig­i­nal­ly designed for a cus­tomer who pre­ferred a pre-cured gel’s reli­a­bil­i­ty but also used a print­ing process.

Because both of the appli­ca­tions are auto­mo­tive, it was impor­tant to have these mate­ri­als test­ed again the auto­mo­tive reli­a­bil­i­ty require­ments. Below are the two data pack­ages for these mate­ri­als includ­ing the rig­or­ous vibra­tion test results:

• Auto­mo­tive reli­a­bil­i­ty test data for one-com­po­nent hybrid gel HT4500
• Auto­mo­tive reli­a­bil­i­ty test data for two-com­po­nent hybrid gel HLT3000
