MF-RC Series
Terminal
strength
With no evidence of mechanical
damage.
Direct load
Resistance to a 2.5 kgs direct load for 10 secs.
in the direction of the longitudinal axis of the terminal leads.
Twist test :
Terminal leads shall be bent through 90° at a point of about
6mm from the body of the resistor and shall be rotated through 360°
about the original axis of the bent terminal in alternating direction
for a total of 3 rotations.
Permanent resistance change when leads
immersed to 3.2 to 4.8 mm from the body in
260 °C ± 3°C solder for 10 ± 0/-1 seconds
The area covered with a new , smooth
clean , shiny and continuous surface free
from concentrated pinholes.
Test temp. of solder : 245°C ± 3°C
Dwell time in solder : 2 ~ 3 seconds
Specimens shall be immersed in a bath of
trichroethane completely for 3 minutes with
ultrasonic.

一直以来，虽然苹果手机在全球大部分地区都很畅销，然而总有一些例外。例如这些年苹果多次想进入印度市场，然而一直都不时很顺利。而此前在阿根廷，由于前任总统发布的迫使公司在当地组装产品的命令，导致iPhone无法进入阿根廷市场销售。不过近日有消息传出，从四月份开始，苹果的iPhone智能手机终于能够在该国进行合法销售。 红色版本iPhone 7和7 Plus 据一位熟悉阿根廷政府计划的人士透露...[详细]
