Smartphones are booming. Their performance capabilities increase with each device generation. The centrepiece of the mobile power packs are circuit boards that are produced with the assistance of a laser exposure system. The highly precise manufacturing process is reliably performed by technically advanced positioning systems.
Pre-harnessed energy supply systems ensure the necessary long-term operational reliability, smooth travel, lack of vibration, and low wear, which is mandatory for cleanroom production.
Whereas circuit boards were exposed with templates in the past, today's process uses special systems capable of high speeds and accuracy, while also being able to produce multilayer circuit boards efficiently. The laser technology-based exposure principle results in a significant throughput increase in the circuit board manufacturing process. At the same time, manufacturing costs drop dramatically: important aspects for mass-producing electronic equipment.
The exposure and laser structuring systems are moved by a complex positioning unit, which can be precisely integrated into the machinery of the overall machinery manufacturer based on the interfaces coordinated with him. Jenaer Antriebstechnik GmbH supplies these mechatronic systems for subsequent installation to an internationally active machinery builder, who exports the complete systems worldwide.
About circuit boards per hour can be exposed today. An aggregate circuit board, also called a blank, is used to surface mount at least 30 smartphones with individual circuit boards with a wide range of circuit functions. Christian Koch notes. The so-called "readychains" have been in production in Cologne for nearly 20 years, and are each extensively tested for their functionality before being delivered within one to ten business days.
The advantages for the customers are obvious: the project planning and primarily the assembly effort drops dramatically. Whereas two particularly quiet energy chains from the E6 product range prove their strength on the approx. Both systems are compatible with cleanroom production conditions. Today, approx. We not only develop drive components, but also supply our customers with complete mechatronic sub-systems for installation into their machinery.
The primary applications include machinery for electronics manufacturing, laser technology, assembly automation, and handling plants. These applications call for high dynamics at concurrently high accuracy.
In the medical technology field, the drives from Jena perform the positioning task for patient platforms in magnetic resonance tomographs, without impacting the imaging process. An important element of the positioning unit is the exposure table. It is sized at 27" x 27". After loading, the circuit boards are processed in the exposure step.
The table is lowered, transported to the rear, and reloaded. A second table has been loaded in the meantime. The exposure process starts over. It is of paramount importance that the scanning process is performed in a completely uniform, jerk-free motion to prevent any malfunction while the circuit boards are being printed.
For the energy chain, this means that it must operate entirely uniform while also being quiet. In addition to a uniform motion profile and smooth operation, low vibration and low abrasion are of essential significance for a malfunction and defect-free manufacturing process.
The so-called polygon effect, which can occur during the rolling action of an energy supply system, is reduced to a minimum. The extensive product range — including for interior separations — supports selecting a tailored chain size. At an inner height of 40 mm and a bending radius of 63 mm, all cables in this application are reliably guided by the Y-axis. The energy supply systems are supplied pre-harnessed. Very little space is available. This is further exacerbated by tight bending radii.
They can also be adapted to specific customer needs. Pre-harnessed energy supply systems dramatically reduce throughput and assembly times. Since cleanroom compatibility is required, each pre-harnessed energy supply system is accompanied by a cleaning record.
System T3 is used on the Z-axis. It also combines smooth operation with a low noise profile. This achieves almost complete resistance to wear, therefore facilitating cleanroom applications. The T band features harmonious and smooth operation, and therefore has extremely low vibration and noise.
Due to the low dead weight, the solution is suited for applications with rather low fill weights and short strokes — even in combination with high accelerations and speeds, which are however not particularly high on the two axis of this positioning system.
We therefore decided to also procure the pre-harnessed cables in addition to the energy chains from a single source. This also reduced the leadtimes in the our production process. However, these can also be adapted to customer needs when required. This is exacerbated in this application by their relatively large number, the tight bending radii, the low space availability, and the low abrasion.
In addition, they also must not influence each other to prevent impairing the long-term functionality of the plant as a whole. The configuration of the energy supply systems changes all the time. We have had good experience with the collaborative effort.
Our local contact is always available to assist us. Among other features, each package is accompanied by a cleaning certificate therefore providing peace of mind with respect to cleanroom compatibility from the start. They provide high process reliability and a straightforward and fast selection based on the desired motion and installation parameters, including cables if needed.
The rolling action of the chain is nearly devoid of noise, a feature that our customers also value greatly. Energy chains applications. System E6. Positioning systems for electronics manufacturing. Pre-harnessed, long service life energy supply systems in positioning systems for electronics manufacturing Smartphones are booming. Reduced effort due to pre-harnessing About circuit boards per hour can be exposed today.
Positioning system for circuit board exposure An important element of the positioning unit is the exposure table. Energy chain on the Z-axis. It is particularly vibration-free and quiet. Each pre-harnessed energy supply system is individually packaged and delivered on-time. Pre-harnessing benefits "Due to our extensive experience, we originally relied on our own cable concept", Christian Koch recalls.

Operating conditions for energy supply systems cannot be more difficult: Extremely limited installation space, long travel and very high friction coefficients. Furthermore, the filling is extremely difficult. The holding times should also be agreeable with all that, or else high repair costs will accrue. Why the rugged energy chains are technically and economically the first choice in the construction of an extendable heavy load transporter is shown in the following article. Because of the enclosed cargo area, it can also be used as a universal vehicle with a payload of up to 38 tons.
Low vibration, quiet, and low wear
Telescopic crowns in adult case with lip and palate cleft. Update on the etiology and management. Facultad de Ciencias Experimentales y de la Salud. Lip and palatal clefts are among the most important congenital craniofacial malformations to be taken into account in general dental practice, due to their high incidence and important repercussions upon the oral cavity. The underlying causes are genetic and fundamentally environmental, and the disorders manifest as early as in the embryonic period. Males are predominantly affected, with a ratio versus females.
