ALPHA HiTech CU31-2030 is excellent for portable electronics
ALPHA HiTech CU31-2030's low viscosity value of only 200 – 1000 cps allows it to fast flow beneath the component at 25.4°C, (see Table 1 below), enabling it to meet high throughput manufacturing requirements. It also meets recent industry requirements for a higher Tg value, at least above 125°C of Thermal Cycling Test -40 +125°C [TCT]. ALPHA HiTech CU31-2030's Tg is 165°C and has been tested to pass 3000 TCT cycles on CVBGA360. No reinforcement gave only 600 cycles pass.
