Causes

Effects

physical damage to components and enclosuresleadto solder joint failure in PCB assemblies ... and degrade performance of electronic components

large panelscan causeboard distortion and component soldering problems

cleanliness testing systemdesignedto remove all flux and solder paste residues from post reflowed circuit assemblies

the number of components , the pin pitch , whether or not the IC packages used have lead , and whether or not parts will be soldered on both sides of the PCB(passive) is primarily set byThe PCB assembly cost ( i.e. soldering on the components

two working benchessetaside for assembly of circuits , with facilities of soldering and desoldering

a fully automatic defluxing and cleanliness testing systemdesignedto remove all flux and solder paste residues from post reflowed circuit assemblies

the cleaning processdesignedto remove solder flux and by - products from the PCB assembly

Higher temperaturescan causevia reliability issues , and solder cracking

an ultra - low VOC aqueous cleaning productspecifically designedto remove non - reflowed solder paste from stencils and solder paste printing hardware

a batch cleaning productspecifically designedto remove reflowed flux residues and uncured wet solder paste from populated printed circuit assemblies

a. Package issuesleadingto unqualified solder paste printing due to PCB oxidation

do you knowwill causeany problems with the PCB fabrication and assembly

passing through a furnacecausingthe solder paste to liquefy and bind the SMD components to the board

heating thermostat heater plate for tv backlightledwelding soldering station ic chip bga solder

Too much of the solder paste volumewill resultin solder short and less of solder paste volume

The studentsdesignedmanufactured their Printed Circuit Board ( PCB ) and soldered all of the connections together

by ionic contamination(passive) caused byreliability issues for PCB Assemblies

stencilis designedfor the solder paste printing on PCB pads

We can helpto design, Fabricate PCB and the final PCB Assembly

to make an informed decision during your next designresultingin more efficient PCB Fabrication and PCB Assembly

An over - rapid heat transfercan causesolder splattering and the production of solder balls

using EAGLEto designPCBs and generate solder stencils

Coupled with increased component density , solder paste sticking to the aperture sidewalls and bottom of the stencilcan causeinsufficient solder paste deposits and solder bridging
