I haven't seen a hydrometer used in years. Are you still foam fluxing? There used to be automatic units available, but with the advent of the spray fluxer, they may have dried up. If you are still foam fluxing with alcohol thinner, place ping pong

I prefer 'YAUC' [Yet Another Unit Converter] by Marius Miller. YAUC converts between many units - Metric, Imperial and others. It supports 585 units, in 40 categories, including Acceleration, Angle, Area, Current, Density, Energy, Force, Frequency

The metioned process will work, but I do have 1 Question, How are the PTH comp. being inserted? If automated insertion is going to be used the process may have to change. Topside SMD - then Auto insert PTH, the reason for this, is depending on the p

First, not that it�s bad, but SM-782, the land pattern standard is a pretty far distance from a DFM check list. Now, if you�d said D-275 er more properly 222X, ama be twitchin� less. Second, your process should include two distinct elements: 1 Data

Hi Carol, Pressure requirements have changed over the past few years. In the recent past, aqueous cleaning systems relied on high flow, low pressure �flooding� techniques. 20 � 30 PSI pumped through large orifice nozzles. With ever increasing boa

Very good questions Bob� Given the fact that my company is a manufacturer of batch cleaning equipment, I will speak more in general terms rather than in specific terms. There are several criteria used in the evaluation of batch aqueous cleaning sys
