0402 chip resistor - settled sideway after reflow

Electronics Forum | Thu Apr 12 01:23:04 EDT 2001 | Eric C

Check the pad size. I had this issue before due to the pad size too wide. R&D had change the size of the pad and is solve the issue. Before the pad size change, I had rebuild another stencil with the pad opening close to the component size. It won't

How do you tell what percent a SMT resistor is?

An explanation that could possibly help (depending on the exact code on these parts) is on http://www.marsport.demon.co.uk/smd/res.htm. The author of this ends the page with a "Personally, I'd check with an ohm-meter!". Daan Terstegge http://www.smt

By resistor packs do you mean SOIC resistor networks ?

1206 Thickness

Electronics Forum | Thu Oct 18 12:58:07 EDT 2001 | jacob

Hello, We recently changed a component on one of our products from a .5% 1206 resistor to a .1% resistor. I noticed that there was a greater rejection rate of the .1% resistor during placement. Apparently the thickness of the .1% resistor is less th

Multiple Resistor Rework

Electronics Forum | Mon Aug 30 08:08:30 EDT 2010 | sreid

Hello, I have been tasked with finding a solution to rework 242 boards that have 34 incorrect 0603 resistors placed. These resistors are placed throughout the board and are surrounded by other SMT components. If anyone can advise me on a more time

Selecte a Shunt Resistor

Electronics Forum | Wed Sep 29 09:57:48 EDT 2021 | zxcvb

I'm attempting to perform power analysis on my target, which operates at 3.3 volts. The average current while running is around 140mA without the resistor. With a 5V power source, I utilized a 10Ohm resistor as a shunt resistor. The shunt resistor w

Axial Resistors in ammo tape, any machine out there to cut different lengths of tape

Electronics Forum | Thu Jan 27 19:01:11 EST 2022 | Claude_Couture

We have to make several different kits containing 5,7 or 17 resistors (axial leads). These resistors are supplied in ammo boxes or reel. We used to cut the tape by hand with scissors, but we need to cut 10000's of these per week. Has anyone ever seen

Soldering of smt Resistor Networks

What is the specific problem? Tell about: * Resistor pack * Board layout * Stencil aperatures

unmarked chip resistors

The difference is that our customer expected these resistors to be marked, and Panasonic's documentation online is inadequate to prove otherwise.

Hello, 1. I have DC engine of car's wishers with I use in at my project. the Engine specification is 12V DC 1.5A. The input voltage is constat of 12V. The problem with adding resistor ( in order to pull down the current)in the circuit is that resist
