Re: Minimum space recommended for thru-hole, pad to pad

Electronics Forum | Wed Jun 23 18:23:32 EDT 1999 | Tom B.

Even though you may find a pad-pad thru-hole spacing, part body size, orientation, and insertion head tooling clearences may be the deciding factor in spacing. 1. Part body diameter will dictate component centroid spacing. ---[][][][

Minimum space recommended for thru-hole, pad to pad

Electronics Forum | Wed Jun 23 15:49:30 EDT 1999 | Kelly Morris

In the IPC-SM-782 (Surface Mount Design and Land Pattern Standard) it recommends a minimum of .040" between bottomside wavesoldered chip pads. Where might I find a similar IPC recommendation for minimum space between thru-hole pads? Does anyone kno

Thermal Residue Fingerprinting: A Revolutionary Approach to Develop a Selective Cleaning Solution

Technical Library | 2009-07-01 09:24:25.0

During the last 5 years, the processes to remove flux residues especially for lead-free and challenging geometries have demonstrated new cleaning obstacles which have to be overcome.i A new methodology has been recently developed to further increase the propensity for successful cleaning.ii At the core of this method is the thermal identification of the residue matrix. Thermal energy changes the physical state, i.e. transitions between liquid, solid and gas phases. By taking advantage of such specific information during phase transitions, the cleaning process can be tailored to such settings, which in turn increases the cleaning success significantly.

Electrochemical Methods to Measure the Corrosion Potential of Flux Residues

Technical Library | 2017-07-27 16:51:57.0

Reliability Expectations of Highly Dense Electronic Assemblies is commonly validated using Ion Chromatography and Surface Insulation Resistance. Surface Insulation Resistance tests resistance drops on both cleaned and non-cleaned circuit assemblies. It is well documented in the literature that SIR detects ionic residue and the potential of this residue to cause leakage currents in the presence of humidity and bias. Residues under leadless components are hard to inspect for and to ensure flux residue is totally removed. The question many assemblers consider is the risk of residues that may still be present under the body of components.
