I look for an international standard for PCB stretch . In case of misplaced solder paste versus stencil we noticed shorts after placement . I found cases where the PCB (image pattern) did not match with the stencil . It was due to PCB or stencil stretch.
	
	
		Philips Consumer electronics mentionned +/-0,075mm between fiducials in diagonal . I've been looking now for an international standard.
