  • Using Rheology Measurement As a Potentially Predictive Tool for Solder Paste Transfer Efficiency and Print Volume Consistency
    USING RHEOLOGY MEASUREMENT AS A POTENTIALLY PREDICTIVE TOOL FOR SOLDER PASTE TRANSFER EFFICIENCY AND PRINT VOLUME CONSISTENCY Mitch Holtzer, Karen Tellefsen and Westin Bent Alpha Assembly Solutions South Plainfield, NJ, USA [email protected] ABSTRACT Commercially available solder pastes use an upper and Industry standards such as J-STD-005 and JIS Z 3284-1994 lower limit for viscosity. Generally, this viscosity is call for the use of viscosity measurement(s) as a quality measured at one shear rate, typically the shear associated assurance test method for solder paste. Almost all solder with a spiral viscometer rotating at 10 revolutions per paste produced and sold use a viscosity range at a single minute (RPM). If the powder contained in solder paste is shear rate as part of the pass fail criteria for shipment and dissolved by the acid activator in the solder paste flux, the customer acceptance respectively. viscosity of the solder paste will quickly increase. If the viscosity increases more than 20 to 30% above the upper As had been reported many times, an estimated 80% of the limit of the specification, poor printing results will be highly defects associated with the surface mount technology likely. The solder paste will not roll evenly over the stencil process involve defects created during the printing process. and apertures in the stencil will remain unfilled, causing Viscosity at a single shear rate could predict a fatal flaw in skips in the paste printing pattern. the printability of a solder paste sample. However, false positive single shear rate viscosity readings are not The purpose of the study was to determine if there is a unknown.

  • Dispensing Solder Paste with a Noflex™ Linear Drive System
    AIRFREE™ WHITE PAPER LDS9000 VS. AUGER VALVE DISPENSERS Dispensing Solder Paste with a NoFlex™ Linear Drive System By: Scott Beebe, President of Fishman Corporation While the limitations of pneumatics in dispensing solder paste are well understood, higher board densities and smaller dot sizes are also challenging the performance abilities of more advanced types of dispensers, such as auger valves. AirFreeTM Linear Drive technology offers promising benefits, including significant savings in material cost and high repeatability without concern for viscosity and the volume of paste remaining in the syringe. The process of dispensing solder paste began with pneumatics. Whether a hand-held gun, or an automated workstation, whether a diaphragm, spool, needle, or piston, such dispensers depend on a column of air under pressure to force material through a dispensing tip and onto a substrate. Heat, moisture, fluctuations in air pressure, contamination, changes in viscosity... all undermine the ability of air-driven dispensers to deliver prescribed amounts of solder paste consistently, especially in the small amounts required by high density electronic circuitry (typically, less than a milligram). While pneumatic dispensers were at one time the only method available for hand-held and automatic dispensing of solder paste, the demand for precise volume control and repeatability led to the development of alternative solutions in dispensing, the most notable being the auger valve. Unfortunately, auger valves have limitations. Linear Drive technology, however, isunique, in that the amount of solder paste delivered—dot after dot after dot—is consistent, by design, and is unaffected by either changes in viscosity (Figure 1) or the amount of paste left in the syringe.* Moreover, cost savings can be substantial due to the ability to pre-package syringes with larger amounts of paste than is possible with other types of dispensers.

  • Making Dry Eyes Ancient History: Egypt, Mesopotamia, India, China, Greece and Rome
    Making Dry Eyes Ancient History: Egypt, Mesopotamia, India, China, Greece and Rome Cheryl Lynn Bergin, OD Author’s Bio Dr. Bergin teaches Anatomy and Physiology at St. Louis Community College. She writes about systemic nutrition, ocular nutrition and the ocular effects of eating disorders. She is a member of the Optometric (Ocular) Nutrition and Optometric Historical Societies. Photo by Stan Trampe ________________________________________________________________________________ Dry eyes are not a new condition, but one might think that the case. A literature search for “dry eye” rarely reveals anything before 1970. One must be an ocular archeologist to discover how the ancients treated “irritated” eyes, dried by the harsh conditions of the desert sun and sand. EGYPT: In 1872, Georg Ebers, a German Egyptologist and novelist, discovered a collection of Egyptian medicinal recipes later called the Ebers Papyrus. The papyrus also contains ancient ophthalmic treatments. Ebers selected the important chapters on ocular diseases, translated them and added explanatory remarks. Written between 1553 and 1550 BC (1,000 years before Hippocrates), this is the oldest book on medicine (perhaps the medical textbook of ancient Egypt). It is similar to the Greek manuscripts about folk medicine that can be found among the collection of Galen and Oribasius, as well as among the manuscripts of Dioscorides. According to Ebers Papyrus, “The water within,” i.e., tear fluid and mucous secretion, is treated with incense, myrrh, and lead salt.”6,9 EGYPTIAN EYE MAKE-UP: Liz Taylor as Cleopatra16 The ancient Egyptian’s eye make-up was not just stunning, it was functional. It helped alleviate irritation from the sun’s glare off the desert sand and even prevented eye infections.

None. CDER Data Element Number. C-DRG-00201 Data Element Name. Dosage Form. Data Element OID: 2.16.840.1.113883.3.26.1.1.2 Data Element NCI Concept ID: C42636 Version Number. 008 Description. This standard provides for all drug dosage forms. The granularity of data often requires that more specific dosage form terms be stored in automated databases than are represented in publications. These dosage form terms are available not only for use in databases that track approved drug products, but also for drug products such as: those that have not been approved, investigational drug products, homeopathic drug products, biologic products, veterinary drug products, and bulk drug products. A ‘use restrictions’ column is being added to help identify where a particular dosage form set or subset should be used (a=CDER Databases, b=NDC Directory, c=Orange Book). The definitions for Lotion, Cream, Ointment, and Paste were revised on June 21, 2006 to include information that would assist the user in differentiating between these dosage forms. These changes were the result of discussions during an FDA Advisory Committee with an open public forum, scientific studies that were published in refereed pharmaceutical journals, and internal discussions by Agency personnel, including the usual adherence to the criteria that are specified in MaPP 7600.4. A 1999 Food and Drug Administration Draft Guidance for Industry states: "A dosage form is the way of identifying the drug in its physical form.

  • Natural and Synthetic Polymers Used in Bioadhesive Delivery System
    INTERNATIONAL JOURNAL FOR INNOVATIVE RESEARCH IN MULTIDISCIPLINARY FIELD ISSN – 2455-0620 Volume - 3, Issue - 9, Sept - 2017 Natural and synthetic polymers used in Bioadhesive delivery system Twinkle K. Prajapati1 , Mrs. Kaushika S. Patel2, Dr. shreeraj shah3 1M.pharm candidate, 2Assist professor, 3 HOD(Pharmaceutical technology), 1, 2, 3 L.J institute of pharmacy Ahmedabad, Gujarat, India. Email - [email protected], [email protected], [email protected] Abstract: Various biopolymers show the bioadhesive properties and have been utilized for various therapeutic purposes in medicine. Bioadhesion can be defined as a phenomenon of interfacial molecular attractive forces amongst the surfaces of the biological substrate and the natural or synthetic polymers, which allows the polymer to adhere to the biological surface for an extended period of time. Bioadhesive polymeric systems have been used in the development of products for various biomedical applications and surgical glue. The bioadhesive polymers can be broadly classified into two groups, namely specific and nonspecific. The specific bioadhesive polymers (e.g. lectins, fibrin) have the ability to adhere to specific chemical structures within the biological molecules while the nonspecific bioadhesive polymers (e.g. polyacrylic acid, cyanoacrylates) have the ability to bind with both the cell surfaces and the mucosal layer. The use of Mucoadhesive polymers is for the development of pharmaceutical formulations. Various other polymers which have Mucoadhesive property are HPMC, PEG, tragacanth, sodium alginate, guar gum, MC, CMC, sodium CMC etc. The ideal characteristics of a mucoadhesive polymer matrix include the rapid adherence to the mucosal layer without any change in the physical property of the delivery matrix, minimum interference to the release of the active agent, biodegradable without producing any toxic by-products, inhibit the enzymes present at the delivery site and enhance the penetration of the active agent.
