What are the feasible options in mounting an alternative component onto a PCB that has a different footprint? PCB redesign is not a good option because the component is used on several other PCBs. The component is very small (8-lead SOT-23) so fabric

Belive it or not, these boards were run through a Centech batch mode Vapor Phase machine. Single stage top side IR preheat. Vapor temp 218 C. Solder paste is an SN62 RMA.The boards were FR4 8 layer w/ solder mask, fairly conventional as might be e

Splitting hairs, I expect SIR of all solderability protection, including OSP, to decrease after reflow. What�s more, I expect the SIR of all solderability protection to pretty much decrease over time. The �comb pattern� test specimens meet requirem

For packages, you use packages names.There is only one SOIC8. The other 8-lead devices are there and it is your job to learn their names. For components descision should be made based you your whole(part number)system.

We have been running a Heller 1707EXL for 8 years and added a Heller 1707MKIII about 1 years ago. We have not had any problems with either one of them. We do both lead and lead-free assemblies along with BGA/LGA components. If speed/volume is not

Hello, I'm looking for a friendly suggestions or best practices for creating Component Database. For example how do you discern different types of SOIC8, with different body size and pitch between leads? How do you categorize and name components? An

We are a tape and reel house,we use a variety of machines. If you are looking for low voulume, low cost and easy set up for you operators. I would look at Systemation MT-30, this is a good work-horse, I have used them for 10years for small runs, no

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

I would assume we are talking about a radial leaded electrolytic cap? We use Electronic grade RTV (Dow corning 3145). It sticks good and can be removed if necessary. It is also pliable so you don't have to worry about CTE or other stresses that may

We need more information to give you a good answer. Is this a leaded part (axial or radial) or smt? How big is the part, how much weight per lead? What is the end use environment, will it see any vibration? or temperature extremes? Some general com
